Meth psychosis can in fact seem that real, and sometimes due to the nature of the hallucinations being around (the majority of people who relay these stories anyway) attracting negative attention, being cracked down on, persecution, paranoia, accusations. Sometimes enough parts of what you're facing here can actually come true to how people will perceive and deal with you. You have to come to the realization next time that you are not actually going through this, and in a more normal state even if you were being watched, persecuted, accused of being heaven and hell itself - it doesn't matter. There is no way that there was a rotating shift around your spot in your room or wherever you were. No one cares that much about some weird tweaker being fucked up on his own in a room by himself and trying to be quiet whether he's succeeding or not. This is so hard to bring to truth, but I swear to God brother they are NOT after you!!
And if they are - then there's two options here. You deserve the persecution or you don't. If you don't - collect $200 and pass go!
