Weird SP Experience - Drugs and Hallucinations

Just wanted to share my experience last night and see if this has happened to anybody before. Last night I woke up into a SP, everything normal so far, then I heard my roommates talking in the living room. Then, all of a sudden I started smelling (hallucinated) marijuana. I thought it was weird because my roommates don't smoke marijuana. Then I started feeling very affected by the smell, like I was getting high, but it was an immediate reaction, not something gradual. I remember feeling like I was thrown into a spinning movement and I started seeing some clothes that I had hanging in my room like they were big hands and shapes and I saw colors and weird hallucinations. Then, every few seconds, I would just have a split-second of clarity, like I wasn't affected, but I would just switch back to feeling high (I don't know if high is the right word, it wasn't really like getting a buzz, it felt more like some kind of acid or shroom trip). Anyway, this lasted for a few minutes and then I don't remember anything. I have always had SP and hallucinations, but never had one hallucination (the smell of marijuana) lead me to another hallucination (the shapes and colors, etc.) Has this ever happened to you guys?
