That sounds shitty Diamond Dog poor you. I've had some panic attack/ weidness on weed before and its not nice. That spirit stuff sounds really freeky. I can remember one time when I was on this crazy research chemical called 2CT7 I thought of a guy I knew and imitated him for a second when suddenly I half convinced myself that I had turned in to him! My crazy drug period is well and truely over!
My golden rule with weed is that when you first try a new batch of weed is have two hits from a pipe or a bong and wait half an hour to see how strong it is.
