Do you believe you have any mental health struggles? Do you think you might want the help offered at a psychiatric hospital?
Maybe you're dissatisfied or bored with the people you're around, and that drives your desire to be around an abnormal (by social standards, anyway) crowd, as a way of finding totally different personalities?
It might not be a 100% healthy aspiration, here could be a million subconscious reasons for it, so I wouldn't go thinking you're off your rocker. We all have our quirks.
