Have I built a tolerance?

Alright guys, so I am definitely new to this forum so hopefully I am doing the right thing. But basically I wanted to talk about my high. (I am going to leave out the details through my trips so if it seems choppy, I apologize.) And I am thankful for any of you taking the time to read through this with suggestions. Thanks.
 
Question:
So my question is, what could have happened to this intense high I had? Do you guys feel the same high or is it slightly less than mine? Do you think it maybe because I don't focus on the trip anymore? Is it my tolerance? Is this new weed bad quality? Is my lighter burning too much of the weed that I am not inhaling? I also drink a lot of water, can this cause the high to be diminished? These are my questions and I know this thread was long. I am thankful for your thoughts again.
 
Background:
I generally smoke on weekends as a way to relax and reward myself for all the work I have done in school. I love sneaking out the house late at night and realizing that I am going to enjoy a nice bowl. Totally the best time of my life! So basically I have smoked several times now. I have had weed from two different vendors so I have only really tried two types of weed from my understanding. 
 
So lets back track for a second though. My second time smoking weed, I only smoked a little bit of one bowl, and I got a pretty good high. But then my parents came home so I quickly ran to my room and closed the door in an attempt to make it look like I was sleeping. My paranoia definitely went down because I felt safe in my room. Plus my sister was with me (as she was an experienced smoker and she smoked with me too). So we talked a little bit about tarot card reading (which is a lot of fun), then I decided to take out my headphones and listen to some Pink Floyd. It was at this moment that I went from high, to euphoria. As I was listening to the music, I could see shapes all of these different colors with eyes closed. They were not very vivid and I wasn't expecting that, but it was insane how I could essentially see the music. And even the sound seemed to have transformed. Listening to it felt like I was in a world of only music. I felt that I had entered a musical landscape that played all of these crazy vibrations and it was all in 3D. I felt as if I entered a new dimension of my subconscious and it felt amazing. Then I fell asleep and so on. 
 
So now comes the third/fourth time I smoked. At this point I was still using the same stash and it has been about a week or so from the last time I smoked. I was alone this time (I prefer it this way as I focus more on the trip) and I smoked a good two full bowls (more than ever before). After I finished, I decided to walk home. The place I smoke is a very secluded area of a trail. So I have to walk down the trail onto the street that leads to my house. As I was walking, it felt as if the trail was just going on and on forever. I felt as if it would never end, but I still loved the feeling of walking with my limbs just floating off like an octopuses tentacles. Plus it was at night, and I always love it at night. Just me, myself, and some some Mary Jane. Then I came home and went straight to my bed, not to sleep, but to lie down and listen to music. I lay still for a while completely still, and then it hit me so nice and softly I couldn't believe it. As I was listening to the music, I felt like I was actually flying. It is really hard to explain what it was really like, but basically I felt that i have been laying on a cloud. The music had been shaping the cloud underneath me and I was in a new mystical land of vibrations. And this time the colors and shapes that appeared were more prominent. And the music within my headphones made me feel like I have entered a forest that just had positive vibes everywhere. I felt soooooo freaking good. Then, I started to sober up, and now this leads to my question. 
 
So now lets move to the present, I have finished my first stash. I have found another vendor and am using a stronger lighter (BIC) to fight the wind as I smoke outside. I smoke nearly two or three bowls of the new weed, but my highs are not so intense anymore. It takes a while for it to set in, and that feeling of flying is very vague in a sense. I may feel it, but then it goes away after about 5 minutes. And the sounds, they aren't so out of this world anymore. I actually know exactly where I am. Its almost as if I am sober as I smoke. I do it with a friend of mine sometimes, so instead of focusing on relaxing, I focus on talking and doing things with him. It just doesn't feel the same anymore.

Why do you have to make a comment about my age? I am a college student by the way so hopefully that makes you feel better. However, I am thankful for your reply. Problem was that it did not hit me like a Mac Truck. So I am going to assume that this new weed is really low-quality material. And thanks Sleepingblade! Plus, I am a BIO major so I kind of take these little things into consideration.
