I don't know if you have a "safe person" to talk about with this, such as a therapist. it's okay if you don't. You have take a good step, telling us about it. That sounds scary going thru this. I have bpd, too, and I have also woken my bed partners with similar things. Once I pushed a man off my bed because I thought he was a guy on a bus trying to put his arm around me. (I was dreaming and did not realize I was) and I pushed him off the bed, hard. The poor guy woke up, woke ME up, and goes, "Carol, WTF is the matter with you?" Neither one of us knew yet that I had bpd; I had not been diagnosed yet.

You are not the first one who has gone thru this. I don't have really any advice, but I am glad you talked about it. Maybe that is a good beginning.

I am glad your bf is understanding, so was my man, after I explained to him I was having a bad dream. Now we laugh about it.

sorry it's not a real answer. Talking about it can help take away the power it has over us.
