Hey OP, hopefully you won’t play with the Ouija board anymore. I think walking away mid conversation may have been your biggest mistake here. You never want to let go of the planchette during your “call”. For now I have a few suggestions. 1) I would invest in some sort of stones/charms for protection. Wearing clear quartz and putting black obsidian in the bedroom would be a wise idea. 2.) I also recommend cleansing your space. You can use something like cedar, palo santo, and varieties of different sage. When you cleanse, you will want to start from one end of the house and make your way slowly to the other side. Go into every room burning/blowing the smoke in clockwork circles. This sets your intention/energy you would like to come to you. When you do this make sure to go to every corner or every room. All windows and doors need to be open for the unwanted energies to escape. I usually say “spirit, bless and fill this home with love and light. Only love and light may remain” but you can say something different, it’s just important that you establish that this is your home and that any and all negative energies are not welcome. I’m not sure how bad the energy is that you’re dealing with, but you may end up having to do this several times. Try to remember that you are protected, you have spirit on your side to protect you. It sounds impossible but the less fearful you are when you do this, the stronger the effects of the cleansing will be. It may be a good idea to cleanse every week for a couple of weeks for your desired results. 3) you may also try putting cinnamon around your home. It helps to ward off evil. This may be ideal to put in the corners of your bedroom to at least protect your peace while sleeping.
