I've a strange thing going on with me for a long time. When I am alone, a lot of nihilistic, misanthropic thoughts, but when I am with some people, I flip back to another self, more enjoying, and a bit more talkative. When I am alone, my creativity level increases, but with people, my confidence level increases. At times, my dual nature confuses me. Alone, I am smarter but negative, and with people I am more jovial but a but blunt. There's this constant push and pull of thoughts and ideas, and sometimes I just become still, literally. I can't move. At times, I feel as if the dream I had is not a dream but reality, and that turns out to be false. This has been going on with me all my life, almost. Is this a mental condition or something? I am a healthy person, do well in my subjects, but my thoughts encircle everything.
