It’s part of having good spiritual hygiene, but to start with here I’d ask these entities directly to leave you a long and mind their own business, then teleport away from them. If they persist attack. You could enchant a talisman or set up a shield as a personal ward that warns these things thier energy is not wanted and to stay away.
The book mentioned in here by Robert Bruce is a very good basic primer of a more shamanic and direct style of keeping unwanted entities away and dealing with them if they come
^ But I also second this.
In this case you can get into trance where you have more conscious control, go up to one and ask it what it wants and what it is. It might just straight up tell you it’s an aspect of you. Whether that’s true of course is another question and here you have to kind of try and learn as much as you can as part of learning who you are so you can make these kinds of judgements.
