Well, i've always been connected to the paranormal side, when i was little i used to talk to spirit etc. Now i sense them. But i grew up with a friendly spirit and a demon that attatched itself to me. And one day i decided to use the Ouija Board ( The demon situation just got out of control ). I started feeling cold out of the blue, chills, feeling like someone is touching me even when i'm home alone, doors closing etc.
It all starts with lights, chills, and feeling cold. I don't think inteties from a Higher plane " show " themselfs like low plane inteties do. My advice for you would be to do a banishing spell ( banish evil, negative energies or enteties ) and a protection spell. ( Just in case ).
And by the way, do you usually feel like something is watching you? have things moved around? Have you felt a touch, cold, chills out of the blue or even a breath?
