I had the same problem the one time I ended up with weed laced with some angels dust.

It was probably the 5th or 6th time I had ever smoked, had chipped in with some friends for a sack, and didnt think anything of it that the smoke was a different color and didnt seem the same.

I was so fucked up and things were so damn intense that I had to lie down in bed for about 2 hours to mellow the trip, I just could not handle it at all. I was experiencing the majority of the things you mentioned, but the effects didnt last past that night, so I am not entirely sure what it might be with you.
