I just waanted to test my ouija board ,  yeah i have used ouija board before and with my boyfriend whe decided to throw it, yea something happened and we got scared especially when i knowing that our building  us under Ottoman cemetery.  Yesterday i just wanted, just to try it again i don't know why when i trade it the first reply was from the moon .I just ask him what is his name and the reply was Some letters that have no meaning and the last sentence was shut up and the letter m .The next person , ghost told me that he was my angel,but it started to exit the board then i stopt and called my bf.
The phone sounds crackle it wasn't that whey before. Then i saw that the computer and  the electricity flashes and then i got scared a little, my bf started to get angry when he got angrier the crackling grew louder .I couldn't hear him and then i heard something terribly strong like cutting metal and screaming but not normal screaming the screaming whats like from a metal band like fray screaming  but more loud and scary . That aweken my parents My parents they only told me to keep it down  the   screaming lasted only a few seconds, Then the  call was  fine and my bf told me that he didn't even hear my voice ,every time we got  angry mutually  the electricity and the telephone breaks down and i heard the screaming.i didn't sleep today
