I'm sorry that you're dealing with this, but I'm glad that you asked the question!

I'm the same way. Almost every night I have some type of very vivid dream or nightmare, and I wake up feeling exhausted. Even my new meds aren't helping shut that off. In the morning when I wake up, I can remember most details of the dream/nightmare and I sometimes have a hard time knowing what is real and what really happened in a dream.

I can usually find something from my day that I spent a lot of time thinking about in my dreams, and a lot of my nightmares are about my phobias - for example, being stuck in a building with an illness epidemic that I can't escape, or being chased by a murderer.

I don't have any advice for you, but I can commiserate! I don't know what it is about me that causes this, but some days it does really suck
