I dunno man...try it a couple more times and see if you get the same effects. Was it your first time smoking out of a bong? I have a friend who gets fuckin weird when she smokes...paranoia like MAD. and then she always claims she sees scarry shit, like people with knives? I'm pretty sure she's got something wrong with her. Some people just shouldn't be smoking weed...so try it a few more times, and if that shit keeps happening i wouldn't do it anymore.
