Sounds as though you're a "medium", who needs help in controlling your abilities.
For now, I would do a sage smudge, throughout your house. While doing so, in your own words, nicely ask the spirits to "give you some space" or "to leave".
You need time to learn about your abilities, and how to control them.
I'd also suggest mediation exercises, charkas, etc, while a white skull candle is lit.
I'm a bit weak in this subject, so I'll need to do some research and talk to a few people.
Hopefully, I'll gain the help that you will need.

PS - Seeing that you're a part of a coven, you might want to ask them for help, as well.
