Thanks for the replies. I don't know what kind of entitiy it was. It is gone now because we are in a different apartment. But it was a small, ugly creature.. I don't know how to explain it. It was with no hair, ugly face, big stomach, tiny hands... kind of like that. I have forgotten already because this was 2 years ago. The idea for exersices to protect myself is great; Thanks a lot! I will strart trying once again. Has anyone tried the Monroe Focus 10 CDs? I will probably buy them
