HerrDirektor i also can see them sometimes.

when i was younger time. seen before humanoid shape spirits running on the sea surface and it stop to waved at me when i saw it.

also kena disturb by ghosts before, i think you probably know that they speak very fast which makes them sound gibberish most of the times but actually they are just speaking very fast.

and once they physically affected me too, when i sleep with my back on the bed, sometimes kena sleep paralysis, so my mom told me to sleep sideways so the ghost can't sleep on top of you, so that night i try, end up it squeezed me on the side and blow air in my ear just to let me know sleeping sideways doesn't work. the next day my right ear straight feel numb and can't hear clearly for few days.

i think you are also a person who have vivid dreams and can control how your dream goes?
