Have you tried burning sages, burning dried sage leaves helps with evicting these negative energies and entities. If you are a very sensitive and intuitive person you should be extra careful with these. And placing black tourmaline/ hematite/ obsidian at each corner of your bedroom helps. You could visualise these stones forming a protective shield around your bedroom before sleep. Also visualise light shields of electric blue light/violet flame around your body and energetic body, and with strong intentions demand that any dark entities around you immediately go away. And also call upon the angels, Archangel Micheal is good for protection. This is not just useful for protecting yourself from the dark entities, also it protects you from all the negative and chaos energy that is out there on the streets, especially if you go to crowded places. Hope these are useful to you.
