To give a little background, I'm originally from Canada, however, I went to a college in Texas for a scholarship. We all know the state of Texas is very religious and I'm not at all (this will play into affect later).
A bunch of my teammates and I decided to mess around with a Ouija board. One of the girls said she used to do it all the time and there wasn't any harm in it. So we decided to go to a graveyard that wasn't too far from us (YES, I know... A Ouija board and a graveyard... Excellent choice *sarcasm*). We set everything up - the Ouija board and candles.
The night was very warm and no wind. We all placed our hands on the planchette and started asking questions. We probably asked about 10 questions and nothing was happening. So one of the girls started saying this is BS and it's all fake etc. As soon as she finished saying that, the board started moving and spelling " GET OUT" and suddenly the candles all blew out. I don't think we have all moved as fast as we did that night to get out of there.
2 days after that night, I started waking up around 3 - 3:30 am. When I would wake up, I could see this dark figure in the corner of my dorm room and I would stare at it but it would never move. Then all of a sudden I would have an urge to throw up. This happened for a week straight. I never told anyone about this because I didn't want anyone to worry.
One night I ended up going to one of the girl's hometown since it was thanksgiving and when I walked into the door I noticed a cross statue (it was beige and made out of ceramic) - I suddenly had an urge to touch it. So I did - mind you, I am a very non religious person and for me to suddenly get an urge to touch a cross is very out of the ordinary. However, once I did that - I felt a million times better... Like a Weight has been lifted off my chest.
Ever since that day - I have never encountered that shadow figure again.
Any thoughts as to why it attached itself to me?
Although I agree with the following statement:
"Ouija boards serves as a gate through the living and the dead. It should be used with precaution and with proper knowledge", I don't think that it is necessary for a medium to be present during an OB session.
"the moment you allow yourself to use it, you allow spirits to manipulate/enter your body too."
Actually, the Ouija board is only a tool to communicate with spirits and, like any other tool, it is important to know the proper way to use it. Any user should keep in mind that they could establish contact with a spirit that they didn't summoned and could be a nasty energy pretending to be someone else.
As far as I know, not every single person using the OB is at risk of being possessed by a spirit; what it is more likely to happen is for the spirit trying to gain the person's trust and grooming them before taking control of them. But a person with the right knowledge will know when to stop contact with an unwelcome entity.
"usage and how it works depends on what board you use. For example, Ouija board that uses a coin is different with a Ouija board that uses glass"
Actually, the above factors do not affect the purpose of a Ouija board (communicating with spirits), even the planchettes or pointers of commercial and mass produced versions of OB may differ from one brand to the other without affecting its performance.
In my opinion, it's better to leave the departed ones alone and treat them with the due respect, there's no need to disturb their rest.
It seems like the OP learned the lesson the hard way.
