I’ve had anxiety and wakeful dreams both together for 2.5 years now. I think mine was triggered by severe sleep deprivation to the point of hallucination. The dreams were bad for the first couple of weeks but I made nothing of them and although I kept getting woken up by dreams, the eventually become pretty neutral. However, lately, for some reason, I have developed a fear of them and altough bad dreams are so rare, I seem to be scared of the idea of dreaming. This has reduced the quality of my sleep, but I’m just about able to get enough sleep so I can feel fully functional throughout the day.
I don’t fear waking up in my dreams and not be able to escape. In fact, becoming aware that I’m dreaming(also known as being lucid) is quite fun and this for me has been the only plus side of these wakeful dreams, but this doesn’t happen anymore. Maybe you haven’t had a lucid dream yet, but waking up in a dream and realising you’re dreaming, you can then go on and do fun things. Fly, ask your brain questions and get interesting answers, see people you don’t see anymore and hear their voices again. Maybe that will provide some motivation that may help you got over that fear.
But for me the problem has become the very idea of dreaming itself regardless of whether the dream is bad. I don’t want this to be the case because the last 2.5 years it wasn’t a problem at all. I haven’t been seeing anyone for CBT yet but hope to soon, and I’m also going to be starting meditation since I think it’s hyperarousal that is waking me up in the middle of the night.
