Sorry I cant chat here yet.
Is this the rite site to ask about ghost.
I see and feel bad ghost. Are they real? How do I deal with that?
No, unfortunately we won't be able to help you.
The policy of this site is that we cannot accept "self help" questions and if you are seeing "bad ghosts" which are disturbing to you, you should seek help from a medical professional/psychologist/therapist.
I wish you the best of luck!
I think Josh summarises your question well regarding the self-help aspects.
That said a few questions that might be on topic for this site related to ghosts:
In general, whether ghosts are real is not on topic on this site. However, the belief itself could be on topic.
