ive never herd of full blown hallucinations but once i was in the woods at like 2 in the morning tokin withh 2 of my buds and one of them wasnt smoking and me and my freind who were thought we saw flashing lights and we looked up over the embankment and swore we saw a cop with a flashlight but when our non-baked bud checked it out he didnt see anyone nor didhe see the flashing lights ... maybe were just paranoid maybe we were just trippin
