Since I moved in my new house (which is easily over 100 years old...) I've been seeing so many weird shapes at night floating around, and alot of nightmares in which spirits are attacking me. I know that the last owner died here at 80-something, and I was wondering if there would be a way to get the spirits to leave me at night. It's been hard to sleep.

Just ask them to leave you alone at night. Tell them this is new to you and if they have to contact you to be gentle. Ask them during the day. Acknowledge their presence. And say Thank You. Ask your spirit guide to protect you. Imagine a white light protecting you. Do Not be afraid. They just need to say hello. Be acknowledged maybe tell a story.

Spirit guide?

I've tried shielding, but I'll have to try talking too.

They usually appear as dark blobs floating around my room but one was a bird? Well I had a bird in this house (not too new in house, about a year) that died really fast tho, so maybe that was tweety? Hmm...

Acknowledge their presence, then asked your Spirit Guardians for protection and guidance as to what or how to deal with them. Ask your guardians what is it that they want. If they need to see the light, light a white candle for them, then pray, and ask if this gives them comfort.
