So what are you doing in the way of banishing and cleansing?
Personally, I am VERY protective of my space and my energy, and I drive everything uninvited away, and put up wards so they can’t come back when I’m not looking.
We have some info on protecting your energy here:
Pay close attention to how you FEEL, about it… based on this post, you’re not too happy about it, wary and uncomfortable. That’s enough info right there imo that either you’re not ready to talk to “rondoms” as I call them, or it’s got … meh… intentions and you can feel that.
If you start feeling dread and anxiety for no reason, that’s a sign of psychic attack or malicious presence. You’re not describing that, so I’m not expecting too much trouble at this point.
If you’re not sure if a feeling is you or externally produced, go outside, breathe and ground, then go back into it. If it comes right back you will now be able to tell it’s not your feeling but coming from the presence, and you can take steps accordingly.
TL;DR Tell it to fuck off.
