my cousin lives with a ghost in her house. they made an agreement: he wouldn't hurt anyone, and she wouldn't trouble him. he helps watch over the kids and is generally helpful.
i have seen ghosts, i don't know what i actually 'saw', but i know it was 'real'.
before my brain damage i was very 'psychic'. not going into details, but i didn't live in the same world as most people. then when my brain was damaged, i lost those abilities. i therefore concluded that it was some function of the brain that made me different. not that i was malfunctioning, but that other's were unable to perceive.
please do not fear what you cannot see. be as kind as you would to any other person, as amazed as you would be at any other phenomena. these things may be a result of energies you are creating, or they might just be revealing themselves to you. either way, they are educational.
i hope you find peace, and the causes of peace~
