Doing so lets them in, if they're already there than it gets them closer to you. I've done it, you hear a voice in your head which is not your own - that is dangerous! That alone tells you something is wrong and can lead to furthur manipulation. And, if they're the right kind you will heat up physically! You'll know the bad kind cause you'll be drenched in sweat when you've done writing.

Please, if you believe you're being haunted or attacked DO NOT AUTOMATIC WRITE.

These damned things are real and they can cause you all kinds of harm if you get too close.

PM me if you have any furthur questions.
