if i ever do "hallucinate" its very mild seeing how weed doesnt normally do that to a person. id say the most common are sound hallucinations like ill think my phone is ringing but it isnt at all or ill hear someone call my name and nobody did. For visual hallucinations ive seen like this really hard to explain mini grid style tornado goin on in front of me....very weird...

but yeah it takes a whole lot of weed to start getting wacked out like that.
