Okay, I don't know if this is the right place to post and ask about this, but since lucid dreaming is a way to astral project I figured it might be a safe place to start.

So a couple of nights ago I was lucid dreaming for fun, running around doing dream stuff, and I think someone might have entered my dreams. I am pretty sensitive to things around me and I felt someone or something enter my dreams. ( later on there was a witch lady who I couldn't make disappear until after I woke myself up )

My question is, can people accidentally (or on purpose) enter your dreams while they astral project, and slip past your safeguards?
I was freaking out because "We" were locked in a battle for control over my dreams, and I couldn't get rid of her.
Usually I have no problem with this but since I am more self taught on a lot of things I was hoping I could get an more experinced persons advice.
