Similar the above mention:
… you’re developing the visual astral sense.
Possibly. I’d say run with your own intuition here… In this case your spiritual hygiene is shot to shit and you have to fix it - banish and cleanse then set up wards to stop unwanted dead and another astral time-wasters from causing you issues.
Cleansing, banishing and setting up a ward is so easy to do and will save you a whole mess of worse problems down the road, it’s worth having these as basic skills you can use in a heartbeat.
