Crazy moods just happen. There's no reason and nothing you can do to prevent them, set off by some of the simplest things like, a song, a joke, something somebody says, or a number of other things, they make you laugh, dance, get silly or make you perform other uncontrollable acts. Maybe it's a human reaction to just have a burst of fun amidst all the sadness in the world, to let yourself let go and enjoy some fun in life without any boundaries. Crazy moods can last for hours or even a day or two, my recent crazy mood occurred from a song by Rick Derringer, it popped into thoughts and then I just had to hear it, from there it was crazy mood madness--singing, imitating and laughing a lot--so far it has lasted two days, but there's nothing I can do but enjoy the ride.Listen to the song, maybe it will throw you into a crazy mood.
Love, laugh, sing and enjoy the moment.
