Is it normal to not control destructive thoughts

Ok so a coworker who was on pregnancy leave came to visit at work and brought her little bundle of joy for all to see, and she basically handled the baby over for me to hold (it was rude to say no) and the little thing was SO tiny and fragile, weightless, and i couldnt help it, i kept on thinking of it dropping, of throwing it, of swinging it, the most destructive thoughts, to feel its weightlessness, i know i know, how horrible to think this way BUT! i would NEVER do such thing, never, but the thoughts are so persistent and i couldnt control it. is this normal?

also, whenever i see anything fragile i just want to break it. like when i see people in short shorts who have super skinny spaguetti legs, i get the urge and thought to just break their legs like a stick in two

this goes beyond people, when i walk down a long plight of stairs it crosses my mind at least once that im going to fall and tumble down the stairs, and when i see a finished work of, lets say, a sand castle, the sand, so fragile and malleable, i want to slap the sand castle to its original mess,

lipstick too, how soft it is, ive bought cheap lipstick, pressed and crushed it on paper just to feel its soft texture, same with eyeshadow, digging my nails on it, to a powdery mess.

i've always had these thoughts since i was little, but, is this normal?
