Interesting but frightening first experience with weed

I have heard that you should never drink alcohol before smoking weed, however one of the girls I was with the night that this occurred, she was a huge weed enthusiast and would not shut up about it with me. I didn't plan to smoke weed that night or ever in my life, the idea of trying it didn't appeal to me, so I had drank alcohol prior because I had made up my mind that I wasn't going to try weed for the first time that night, or ever. However, some time after I drank a considerable amount of alcohol (I believe I was sobering up at this point), this girl was adamant that I give it a go, that I didn't realize what I was missing. I was getting sick of her talking about it so I finally took a deep puff to shut her up, and she had me take a second deep puff.

After I started experiencing the effects of it, I instantly realized that I'd made a mistake. It was the worst experience I'd ever had. I didn't know exactly what to expect, because you can't know till you've done something. I did not like the feeling the weed was giving me, which felt like I was "floating" a few inches above my physical body (I understand now that this must be why they call it being "high"), and like the weed was trying to give me an out of body experience. It felt like my mind, soul, consciousness were trying to go off somewhere in oblivion, trying to float away somewhere, trying to enter some sort of "energy" state of being, much like the energetic world of "thought" and energy that you enter when you're in the dreaming sleep state. Basically it just felt like my consciousness was trying to slip away.

So I started having a panic attack, we're all used to the physical/matter state of consciousness and I'm no different. I thought I could die from a heart attack with how terribly fast and hard my heart rate was going, coupled with incessant sweating and feeling like my body temperature was dropping dramatically and feeling cold and shaking really bad (probably not just because I was feeling cold but as a panic attack side effect) when it wasn't actually cold in the house I was in. Every time I'd look in a mirror I'd see that my eyes were looking in slightly opposite directions, which I thought was very odd and I just didn't look normal. Eyes were really red and bloodshot, and I was just freaking out really bad, not quite as much about these bodily symptoms I was having (my heart pounding and racing really bad, the sweating, feeling cold and shaking, eyes appearing to look in opposite directions) as I was about this feeling of my consciousness trying to float or slip away that I was trying to fight. I felt like a vegetable, couldn't respond with full sentences or pay attention to anything anyone was saying to me, and from what I understand this is something that is typical of a maryjane high.

One thing that also bothered me while I was high was that my boyfriend at the time kept looking me in the eye and telling me to "stay here" and I took that to mean that I had gotten too high and that if I didn't focus on being present in the moment and "stay with him" I could lose focus and lose my grip on reality, and I could cease consciousness and die, or something. I don't know what I was thinking, I'd forgotten in my panic of the moment that I'd been told you can't die from weed and that weed can't kill you. I found out later from him that he simply meant "stay put, don't go anywhere" in the physical sense. Don't know why he kept saying that to me, I was clearly going nowhere and was in a vegetative state (or so it felt), and it took so much energy to move at all that all I felt like doing was staying put, clearly he would have known this because he'd smoked weed on many occasions before and knew its effects on the person high on weed.

I'm just trying to understand what happened to me that night better. I asked something about this somewhere else online and someone had responded that what I experienced, my symptoms/side effects, were not common and are actually atypical of being high on weed. I'm very much a newbie when it comes to drugs and weed, I've drank alcohol on many occasions throughout my adult years, as I drink in moderation when I have the chance (not too often), and I'm fine and comfortable with alcohol's drunkenness effects on me, it's very different from how a weed high feels. I don't feel like I'm "floaty" or like my consciousness is "slipping away" or like my soul is trying to enter some etheric realm, when I drink alcohol. The high that weed gave me as a first-time user felt almost similar to that of when I felt like I was going to lose consciousness once when I was in the process of donating plasma and I hadn't drank enough water or ate enough healthy food beforehand as I had been in a rush to make it to my plasma donation appointment, and I felt dizzy, sick, and uncomfortable before the phlebotomists came to my side to return my blood and plasma back to my body.

I read something interesting online one time saying that when you smoke weed, you're actually giving the plant a part of you in exchange for you experiencing the plant. It was something like that, I can't remember the exact words. Can anyone tell me anything more about what I experienced, if the side effects were even common or typical of being high on weed (especially for a first-time user experiencing the greater potency of weed), if what I experienced happened because I drank alcohol before smoking weed and tell me why drinking alcohol before smoking weed is discouraged, if it sounds like the weed I smoked could have been laced with anything (I know nothing about the weed I smoked, I simply smoked it and assumed it was purely weed), anything about the spiritual effects of being high? Does being high on weed, especially for someone using it for the first time and experiencing its effects potently, give you the actual feeling of what dying feels like without actually dying, or is being high on weed not at all representative of what dying feels like (without the pain that one might feel during the death process)? It probably sounds odd that I'm associating being high with death, the reason why I ask about that is because it seems to me like marijuana high is a very spiritual experience and the side effects of being high, especially the "consciousness slipping away" part, I couldn't help associating with what dying might possibly feel like. It also seems like a very "mind over matter" drug, I was high all night and if I hadn't finally gone to sleep, I'm sure I probably wouldn't have came off the high till I eventually got some sleep to get my mind off it. I'm anxiety prone and think too much sometimes, and I think that's probably why it was such a bad trip for me.. it seems odd to me that so many people love the high that it gives, honestly there's almost nothing more frightening to me than having that experience again. I'm very intrigued by weeds' effects on the mind and that's why I'm so detailed about all of this. It gave me none of the euphoria, enjoyment, or relaxation (or maybe I did experience the "relaxation" but I worried that it was relaxing me "too much" and I had an adverse reaction of panic instead), I understand that everyone's experience is different, but this was mine and I almost never hear of anyone who's had a bad experience smoking weed, so I just think it's really interesting.
