The only psychedlic experience I've had with cannabis came after smoking a couple bowls of AK47 with some friends. Shortly after I felt as if I were falling through the counter I was leaning on....in to some other place...then only to look up and recognize I was still at the counter. This was a continued pattern, and finally after I came out of it I realized just 2 minutes had passed. After that things were pretty chill though. But this was the most intense hallucinagenic experience I've had with weed.
