Seeing things?

I dont know how it happened but ever since ive started smoking weed i keep seeing thing run past me but there not there, is it possible i smoked sumthing laced and it pickled my brain a little or sumthin else?
has this happened to anyone else or am i crazy?

I'm in that club.

I never really see the "thing" it's just a blur. But I notice it often

its probably just a ghost don't sweat it.

ya man its weird i sure would like to figure out what caused it

Its probably because you smoked pot..... Pot does that.

Seeing dead people...........
