Paranoia seems to be something "
characterized by suspiciousness, persecutory trends, or megalomania" (Merriam-Webster).
Consider asking yourself this question: "
Can I justify my paranoia?"
The act of re-framing an idea based from someone's paranoid interpretation can only occur if you can introspectively acknowledge observable rational facts constituting your supposed paranoia. In other words, if you can rationally justify being paranoid about something, then it's not paranoia, but instead,
defensive caution.
If, however, you find yourself in a room with no windows, doors, cracks, etc., and you still find yourself suspicious of someone watching you, then there better be some hidden camera behind a painted lens because otherwise, this would be a form of paranoid schizophrenia. I'm sure there could be other diagnoses as well if you had an actual mental health professional reading this, but all-and-all, I doubt this fits your M.O., especially if this behavior you find yourself concerned with has yet to affect your everyday lifestyle.
Rest easy, my friend. :.)
