Suddenly get overly exited about small things

I get overly excited about small things (for like a second)- For example every time I listen to dubstep and the beat drops I get exited and make weird expressions. I know this because one day in school we were not doing anything so we started listening to dubstep music and when the beat drop I got exited and my friend was looking at me and got scared and asked if something was wrong,she told me I rolled my eyes a bit and jumped a little. This not only happens when I listen to music but also with small things like imagining the wind on my face or jumping from a high place..Is there like something wrong with me or am I just tripping (btw I don't do drugs or anything lol)
