Is it normal to do something because i thought of it?

There have been times where I have done something impulsively simply because I thought of doing it. A couple examples and times I have been to the hospital were, stabbing my hand with a knive, punching out the bathroom window, putting my hand in the fire, and other various things that resulted in stiches or other misfortunes. All these times I was not angry, depressed or any other reason than I just thought of doing it so I did it. Other examples are lighting the curtains on fire in the house, using the bow and arrow in the house, setting off the fire extinguisher in the house, throwing stuff at the neighbors house, etc. I do this stuff all the time. Its like I think about it, so I do it. I actually have a lot of self control because I think about way worse things than that.
