You know how hard it is to visually hallucinate without spending money? (With the exception of pressure hallucinations, when you press your eyeballs for several minutes then let go and see geometric shit)
Nearly impossible. Because if you fuck up any of the free methods even slightly you are either getting buried (expensive) or in hospital (expensive). That includes genetic hallucinations, which they make you pay for meds for!
I hallucinate (I have a chronic headache and migraine condition, so I’m prone to such things), but it’s mostly olfactory, so mostly I smell peanut butter when there isn’t any. Not really fun or interesting, and I hate peanut butter. I’ve also recently started auditory hallucinations, but only hearing my deceased cats calling for me or video game music on repeat, again not interesting.
