The tale of The Possessing Ghost

Can someone take this and make it better?, i had this idea while staring at nothing for 2 hours, but i lost my motivation, it wound be better for some one else to take it, im better at oneshots then long stories (not that i have made a oneshot)

A story about a boy who is bored of life, decided to experiment, "energy cannot be destroyed nor created, only transformed, if humans are made of energy, the body, mind and spirit, does that mean a human who dies will get there consciousness transformed?"

and since no one volunteered, obviously, he experimented on himself, but he won't commit suicide, oh no, he'll find someone else to do it, so just in case he turns into a ghost he can just posses him.
