Me, all my life been able to see the preternatural stuff, thats why Im strong advocate of "dont play whit that" and respect the spirit world person. I also bottled all these things for years because nobody believed in me except for my other 2 sisters (but we had no one to understand us or take us seriously) so I kind of believe in your friend's experience is real since she bottled that up for so long. Is hard specially when you dont undrstand what happened either.
Summary
My first encounter with a ghost was when I was 4 and enterd a room I wasnt allowed to enter if someone was renting it at my grandma house. But that day was ok since the last tenant leave and we will clean for next tenant. But I went alone and saw a man, he looked back at me and he got mad at me for being in his room, suddenly a lady with long dress told me to leave. I was scared so I ran and told my grandma. She kept silent for some minutes after asking mw how they looked and I described them and she said they were her parents, my grandgrandparents that was their room.
Thorough all my experiences in life, I began to differentiate people souls, demons and their subalterns, bad spirits, nature spirits, angels, God.
My siblings, mother and I are prone to see these stuff but I guess im the stronger here and the only who has seek professional help (no witches or other weird stuff that only steals your money, for that Im able to do a better job than them) and I took that from my dad's scientific mind, to check out things first before coming to a conclusion.
I cant always see them, but I can sense or hear them. So, its not exactly as in "Six Sense" but more natural???
In that matter, one of the scariest situations I was involved was when one of my ex-friends father's house was getting more haunted that the usual. She gave me permission to go to explore the house and see what was there. Man, his dad's room was the worst place in the house of how infested it was. I even saw the demon that took possesion of the hoouse I knew that he allowed taht from the person he works for. In other words, he made a contract. The demon did an attempt to made me fall from the stairs. I also found his step-son was playing the oujia and drugging hard. My ex-friend had to move after that cause it was begginign to attack her as well.
Other of my scariest expreiences was when I went with some friends as improntu tourists to another city but we wasnt plannign on staying the night but we lost our last bus so we ended on a strange hostal. I noticed the owners were former communist army people but said nothing. We were asigned to the last room in the aile, closer to a empty lot it took my interest. That night I was having nightmares that the owners wanted to sell my soul to the evil (wtf) and I woke up to a sipirit floating all over me (I moved my hand kinda to slap it lol and with a go away mtf) and noticed a ton of other spirits were also floating over my sleeping friends. For that moment I was like oh Jesus. I had to leave silently the room, it was 3 am. I phone called my ex to calm down and kept awake till 6 am in a chair outside until the janitor ladies came. I told my friends why I did that but they looked at me as if I was a weirdo. When we checked out, I asked the ladies to tell us what happened in that lot because I saw a lot spirits, she were so nervous, looked each other and made us promise not to say a thing to anyone or they could be fired or worse... in that lot were the bodies of a lot of young men that opposed to the communsit regime and they made them dissapear and buried them there... well, fuck. Like that are more young ppl disappeared here thanks commies. My friends finally believed me. I promised not to tell anyone (at least in the country)
When we were younger, my family and I moved a lot. in one of these houses we lived, my sisters and I couldnt sleep a single night cause a demon was always watching us (we decided to sleep all together because we were really scared) till we couldnt have it anymore and begged in tears to our parents to move. next day we moved, the neighbours house was on TV because the daugther went crazy and posseded by a demon and tried to kill her parents.
and so on, i have more stories
Gladly, the firt person that heard me out and believed me began to help me when I was 18, even tho I only met that old man once. I wish he could have thaught me more. Later, the second person who believed me even tho they dont believe on the supernatural is my BFF, she knows if I say something about it its true.I even went to therapy to show I wasnt crazy, yeah and the doc said Im not crazy lol so Im more compfortable now telling people about this and now using my experiences to write some stuff on my story "Die Instrumente Gottes"
