Do you, did you ever have any odd dreams after therapy sessions?

After my session last week when I offloaded a great pile of toxic memories of my Mothers physical and emotional abuse I came home feeling emptied and calm but that night wow....

Buildings falling in a city scape, buildings with big skeletons sculpted onto the outside and me running like a little ant through them all as they toppled and roofs caved in and glass shattered and then holes in the ground opening and swallowing the ground. This was followed by a tsunami, a literal wall of water smashing through everything and carrying it away.

I woke up thinking WTF was that all about? I rarely have nightmares but this one was a humdinger at one point I looked down and my hands and feet were cut and bleeding. I wondered if anyone else had found that therapy creates mad dreams or nightmares and I wondered what people thought of this whether this is a healthy part of the process of spading through the locked in 'bad' memories or if this is a bad reaction to it.

I'm going to talk to my therapist about this next week. It felt very scary at the time but in the days after I felt mostly OK in my day to day and I'm wondering if this sort of dream is just the subconscious getting on board with the walls coming down and me letting the stuff out to a therapist.

Has anyone else found that disclosure creates big scary dreams? I am worried as to whether this is a sort of positive aftershock to be expected or if it is a sign that I am going to places I shouldn't with therapy.

I know other peoples dreams are a bit boring, but if anyone else has had an experience like this or has an understanding of why can happen I'd like to hear from them.

Thank you
