Opinions - Time passing?

[accessgranted]

Iv never had Salvia Divinorum however swim has seen others take it and i know it does not last long when your watching a person.

Just out of interest does the trip seem to last a long time? the reason i ask is because in my beliefs there is something called astral projection which works on ther theory that the spirit leaves the body and can travel and be gone a vast ammount of time but only a few seconds would have elapsed so when the person woke up only a few seconds would have passed but they could have been gone much longer.

When other swims trip does it feel a whole lot longer then just a few mins?
