I suffer from insomnia so a good nights sleep is very important to me. I’ve been on sleeping meds for 20 years.
The only problem is every night I have disturbing nightmares and after having them repeatedly I say f@#k it and wake at 4am and nap during the day.
I have a stress free life thanks to my wife, kids and meds. I had a trouble free childhood. No trauma. Generally happy with my environment. Apart from sz which is medicated properly and eliminating all stresses and triggers I don’t know what to do.
I’m waking several times each night with a cold sweat and a brief memory of the nightmare which can be repetitive or random.
Maybe you have some underlying emotional trauma you could benefit from talking to someone with?
I personally think a lot of dreams are a window into your inner thoughts.
You could try logging your dreams down in a journal and see if there are any repeated patterns.
I also agree that some sleeping pills do cause more vivid dreams.
