Psychic bullying

The question "What is psychic bullying?" prompted me to answer.

It’s when a person, who is able to communicate with the dead, is being harassed and bullied by spirits. It could be a whole group of them that do this against one person. The psychic may be unable to block out the cruel words and can’t help but hear nasty things said about them. It could be something else too.
Poltergeist activity. Some people may be living under fear of unseen forces. Someone needs to understand why this happened first of all and what woke up this energy in particular. Usually it’s a ouija board that unlocks a door.
Psychic bullying can dress itself up as mental illness, or psychosis. For example, vulnerable people who are ill, on drugs or women that just gave birth to a baby, would be open to dark entities. They would feel a sense of dread, and be tricked into thinking those entities are benign to win trust and then become under their control. Spirits of a sinister nature can cause brainwashing into individual people.
Finally a spirit or spirits who have complete control over a person’s life, and dominate how the person should be every day. Choosing what they should eat, wear, watch on TV, read, ect. This is usually vulnerable people with mental illness who suffer psychic attacks like this from sinister entities.
