I am 20 years old and I believe I may have some sort of health/medical problem that I am unaware of. I have never really talked about it to anyone. I am too embarassed to actually talk about it and I guess I never really realized that I may have something. floor. When I listen to the music I would imagine the person singing in my mind like I was the one in the concert or something. I use to act out scenes from shows and stuff in my head and talk aloud while I also would do the floor thing. I did it when I was young, so I never thought nothing about it, but it embarassed me when my dad or mom would walk in and see me doin it. The last time I did that I believe was maybe a year ago when I was alone, but I still regularly get excited and shake my hands and my friends even notice me making faces occasionally and tell me I dont even notice Im doin it. I can think something and get excited about it and sometimes I notice, but I guess its second nature for me and I really look stupid.
