Was my weed laced?

I smoke pot. I smoke a lot of pot. I also have done mushrooms. I've been so high I can't talk and feel like I'm floating. I had a lot of pot last night, and it seemed off from the start. First off I moved and don't know the guy I got the pot from. Second, I use a vaporizer. It usually hits between 370 and 380F but last night it was hitting between 350-360. There was a lot of white vapor. I had two hits. Not too long after that, I started tripping really hard. It felt like I was on mushrooms. First I started seeing little patterns around the tv, but not too many hallucinations. Mostly I felt pins and needles and a lot of heat rolling over my body. My neck started tingling (this happens to me before I start tripping on mushrooms). I started experiencing synesthesia and felt sick to my stomach. I got very sweaty (so far as I can tell, all my senses were mixed up at that point). I started experiencing time out of order and slowed down extremely. I felt connected to the world and then I started tripping balls. I don't know how to describe it, I hallucinated I was having surgery, and then I was back home and then I died. I went to the bathroom and put water on my chest. I lay down and started shaking all over and having muscle spasms. I came back and tripped some more. After that I started feeling better. At that point I felt very stoned but not like I was tripping anymore. Can weed have effects like this? I find it more likely there was some other substance. What could have happened to me?
