Too High or Bad Weed?

So, this question has been troubling me for some time.
A while back when the semester at my college started I went to the creek to smoke with a buddy of mine. (I say buddy loosely, he's more of a bud-of a bud-of a bud). But we light up and while we're lighting he goes on with all this "The usual shit doesn't get me high so I have to get the strong herb yada yada" I had work in a few so I only wanted a buzz.
I took two hits.
After we were walking back I the intensity of the light seemed to increase to the point where everything was white. I could see the outline of his redish orange shirt but that was it. I told him I needed to sit down and fell over.
Bad experience, I felt sick and dizzy and was freaking- I told him to get me back to the dorm and to put water and food in me now.
I downed four water bottles and ate a couple sandwiches.
After about 3 or 4 hours it faded but when I came down my head was killing me like when I used to get migraines.

So my question is- was it laced or was I just wicked blasted? It doesn't seem right to me but depending on the people I talk to they'll either agree that that was bad or they'll laugh and say "Oh, you just thought you were going blind."

Keep in mind I haven't been smoking too long, since about 15 (I'm 18) and only on stressful and headache filled days. I also don't smoke before bed because I wake up with a headache and nausea.
Any help?

 

But I've been in other situations where I finished of a couple bowls and a bong then went to clubs and parties and such without the same reaction? I though it had might been that too when I looked around- this happened in Sept and is still poking at my thought bones. But maybe it would be something like that..

 

I only get the headaches and nausea in the morning if I don't eat before I sleep and get baked. It's odd I think but I usually avoid the smoking before bed since it's simply not needed for me.
But other times I just get the usual body high, no adverse effects.
