I was thinking about some things that happened to me and some stories of some night creatures talk about and this question came to my mind
Can a thougtform use the negative energy as a life source? If a thoughform lived of negative energy of humans and the dark beings then that creature could not only get strong eneough to make enemies run away in fear because it would get more powerful everyday but it could live forever too.
In my opinion I would be cautious about it.
There is a possibility you can become possessed (not like in the movie) by negative spirits or energies.
IMO you could also pick up negative vibrations that can bring you certain diseases (eg cancer etc).
