In my college years, I met my ex "F" shortly after his mother passed away.  I became very much aware that she was still around the more time i spent in his apartment.  I dreamt about her once and saw her reflection in his mirror.  Around that same time i would wake up often in the middle of the night, unable to move and paralyzed and knowing there was a evil presence in the room.  I believe that my proximity tp death caused a portal for demons to come through and my emotional vulneribilty at the time caued them to be able to know i was there.  Like a lighthouse shining in the dark, my psychic pain illuminated my soul and attracted them to me like ships to a lighthouse. It happened often all that winter and each episode i would experience a completely different entity.  Sometimes it was a black cloud moving on the ceiling, once i saw a little girl holding onto my hand and crying.  I have seen a woman with a candle, and a man with a coat and a hat on.  Each time i know it was not a dream because after they disappeared and i was able to move i would turn the light on and immediately write about it in my journal.  My notes were very detailed.  Then i would fall asleep with the light on.  In the morning, reading my notes proved that they were not dreams.  I know the difference between dreams and demonic experiences.  I became very aware of demons and how they operate.  They aim to impose fear and they take pleasure in terrorizing you.
I was afraid to sleep at night but my ex, who also has had the same experiences, schooled me on how to deal with the entities.  I learned not to be afraid and give away my power.  Long story short- he was arrested one day and "F" was out of my life.  Around that time, i would wake up in the middle of the nights and see a shadow figure standing outside my room watching me.  It would stand motionless there for hours.  It was just watching me.  I dont know how i attracted an astral being but somehow he became aware of me and stood outside my window every night.  It was a tall shadow and i would hide under my covers so afraid of him.  I left home around that time due to family issues but also wanted to get away from the astral being.
