I have had a few cases of paranoia....I was over a friends house msot of the times... And he and I had gone half and half on some killer dank...Well I kept getting these ideas when people looked at me that they wanted me to leave so they could smoke my pot. Well I told myself it was paranoia and I left to come home and chill out.. The next day over half of my pot was smoked, and thats after I confronted the friend about it and he said "Why would I do that?" So paranoia may not be paranoia, sometimes.
