What drug could this be laced with my weed?!

Ok, i never thought i'd see laced weed. And i dont know if i have, but im a regular smoker (about twice a week, on weekends). Well I smoked some weed the other day and my dealer said "i think that weed might be sprayed, check it" and i did, it was ok. Everyone else who had smoked it said it was fine as well. Then i got some more and smoked it today, different strain. I felt high like normal then my focus was slipping away. Then i felt like everything was 2 inches away, the walls were closing in and i could reach out and touch any part of the room i was in. The tv across the room looked like i had my nose to it. And when i laid in the bed to relax, the sheets were overwhelming and i felt trapped almost. I took a few deep breaths and kept saying in my head "im just tripping out" while trying to imagine the room being normal size. My friend said i was acting different and basically just ignoring him and off in my own world. Also i felt like i was entering a new world, like i was leaving the sober me behind and i could see myself 3rd person, and i was going off to this new universe.
