Exactly What Happened?

Hello, I am new to this forum but I have a question about someone I know named SWIM. Today, he experienced something he has never before...

Today SWIM was invited to smoke 2 bowls with two of his friends and another friend of theirs. So, they did and everything was proceeding normal for SWIM. For the first 10 minutes or so, SWIM felt like he normally does when he smokes weed. Now keep in mind that they only had 2 bowls of regs, SWIM has had up to a half-ounce of chronic at once. After about 10 minutes of chilling, SWIM decided to sit down because he was feeling out of the ordinary...sort of sick to his stomach. He sat for about 5-8 minutes, still feeling kind of sick and wanting to throw up. It was time to go anyways, and when SWIM stood up, he felt very "out-of-it," just wanting to go home and lie down. He was feeling so sick by this time that he couldn't even say goodbye to everyone, he just left. As soon as he walked outside, SWIM threw up. SWIM has never thrown up from smoking weed before after 1 year of doing it and having WAY more amounts than he smoked this day. SWIM and his 2 friends were walking home (about a mile walk) and SWIM felt like he transferred into a completely different world. He blacked out for a few and everything was blurry and like a dream. After that was over, everything became more vivid and unrealistic, like he was experiencing the impossible. He still felt sick and all he wanted to do was sit/lay down after about 3 minutes of walking. His friends were talking to him but he simply couldn't respond. This extreme euphoria-like-feeling was not a pleasure either, SWIM just wanted out, quick! Eventually, he started to feel more normal again and didn't even feel the effects of the weed anymore. It felt like he was in this world for about 3 hours, yet it was only 10 minutes.

Does anyone know why SWIM was feeling these things?
