Blended dreaming or just a weird dream?

I had a strange dream about a therapy session in which I had a co-present (I was pushed back over the course of the interactions, less and less in control, but still aware of thoughts and feelings and slightly able to communicate) experience. Elements of my waking surroundings were present (like being in my bed, though it was in a different room). We were discussing dissociation and also a story I have been writing and were interrupted briefly by my toddler and husband being at the door. I (as my teen alter who I've been identifying as my "poet") was very scared and upset because the therapist said the session would have to end suddenly and my head started hurting so badly.
In my dream, my therapist was talking directly to my poet and kept using a name for her that I've had come into my head before without relating it to any particular insider. I could barely hear him. It felt like he was right next to me, whispering in my ear, but in the dream, I suddenly realized it was a phone session and he had never been in the room with me at all (despite thinking he was the whole time). I couldn't open my eyes; I was paralyzed. I still felt like he was next to me, but I couldn't hear his whisper clearly or make out the words...I just "knew" what he was saying. I kept telling him to just go away, that it was too painful, that I couldn't hear him right now. Which is funny, because even though I couldn't hear him, I knew he was trying to reassure me about his having to go. I said, "I can't hear you at all, but I know what you're saying," in a scared voice. I couldn't even tell if I was really speaking or not, could not feel my mouth move, still felt paralyzed. He explained it was because he had tapped directly into a dissociated area of my brain. He kept trying to get my poet to listen carefully to him, so he could reassure us about his leaving. She was too upset and we were shaking with fear, aloneness and pain. We had our hands on our head, trying to push in against the pressure that felt like it was going to make our head explode (like something was going to come out through our forehead).
I couldn't even remember the particulars of what we discussed anymore. I started hearing my daughter at the door again and then over the next minute or so, realized that she had woken up in her crib, I was in my room and I had been in a dream. I couldn't make myself get up and go get her for a couple of minutes after, like I was still semi-paralyzed, very much in a fog. My head still hurts like hell 40 minutes later.

So, my question is, do alters dream? Do they participate in our dreams? Or, is this just one in a series of bizarre dreams I've always had as long as I can remember? I often have "not me" dreams or "part me" dreams where I am both me and someone else, sometimes I can look back and see alters there, but sometimes just random others. What is your experience? I wouldn't have thought much of it if I didn't have the world's biggest headache during and after the dream.

to answer your questions as briefly as possible (i tend to babble lol)

Yes they can interact in dreams and yes they do dream.
i have dreams with alters in them sometimes, they're usually talking to each other.. For me though, this was a new thing and only happens when they're introducing a new alter.... Its kinda like my systems way of testing the waters to see if i can handle another alter...

What your describing sounds like they're interacting with you in your dreams. Weather its to let u know that they're there or if its to give u a specific message i don't know.. i guess that's something you would have to ask them... but yeah, i have those dreams too alot. I wake up and find myself not knowing what was true life or the dream.

i hope this helps some, i think the only way to get any answers is to ask inside.. Or even during the dream; ask the what their names are and what they're doing and why they're there... its worked for me!!

Goodluck with it and sweet dreams! lol
