ok so....i feel sick to my stomach. as i was in bed trying to go to sleep i wud see a huge glow in my window every few mins.i kept getting a glimpse of a girls face. Then i heard someone knock on my room door just 4 minz ago and call my name but noones there. i almost pissed myself lol. nothing scares me but this did.....
i also kept feeling a strong feeling that someone was standing behind me. like the feeling was on the back side of my whole body as if i was cuddeling with someone behind me. before i fell asleep and before all of this it felt like i was tingling inside..it felt great but then felt like someone was rubbing or holding my stomach.
You might have a spiritual entity of some sort on your hands. It can be quite frightening if you're not familiar with that sort of thing. If this entity is making you feel uncomfortable, then look into Protection and Banishment spells/rituals.
One of the most commonly used Banishment rituals is that of Smudging. This can be done by burning White Sage (or typical Sage) and allowing the smoke to enter EVERY corner of your home and property. Sage's energy vibrations is very good at cleaning away negative energy.
Sometimes the smudging doesn't work, however. This can be due to the fact that the entity's intentions aren't "negative" or it is of a stornger velocity. Try the smudging, if that doesn't work; message me. I can offer you additional advice.
As for Protection, a Pentagram is typically used in the Craft as a symbolo of Protection, much like the Cross is used in Christianity. You can also visaualize a sphere of White/Blue/Gold energy around you and your home, protecting you from any harm.
If you don't get ride or help the spirit then it will just keep pestering you until you do. You could try communicating with the spirit but it is kind of risky, if you do take the necessary precautions(protection, enough energy to fight the spirit if need be, ect.).
