So we've got a thread on experiences...but what about your funniest ones?
A friend of mine thought he was a werewolf -- kept howling at the moon and clawing people that came too close to him. Hilarious.
Another friend saw his books fly down from the bookshelf and attack him, then saw the earth in front of him, revolving, with his sister's face on it...he kept trying to reach out to her, but couldn't. He then charged the revolving earth and completely tripped over table. When i mean tripped over the table, i mean a headfirst roll.
A girl at my school was "led" into a trip by some friends and i (we didn't do it). While walking up the stairs, we told her there was water running down the stairs. She freaked out, took off her shoes, and lifted her pant legs. Later, we told her there was blood on the walls and sewage in the hallway. She started FREAKING out! My friend got on the ground and pretended to lick the ground, and the girl almost threw up!
SWIM experienced a "cold" sensation, looked around, and saw that he was in the middle of the south pole. His cigarette turned into a snake, so he threw it at his friend, who he thought was a rabid penguin, even though he could see his friend just fine. Strange feeling.
SWIM's experiences with salvia have all included extreme hilarity...i'd love to hear more funny stories
