Hm... it used to happen with my during my first times... weed would make me concentrate all my attention in one or two senses, and the another ones would vanish... but it was variable, like... first i was all hearing and seeing, then it would change by tasting and seeing, than tasting and smeling, then smelling and hearing again, and so... my senses were alternated at about 1-2 times per second... about the same speed of the frame vision i got... it was TRIPPY... but unfortunately only happened during my first times... and nowadays i would smoke anything to feel like this again... :stoned:
