Does Sleep Apnea cause weird dreams?

Hello @loribroda, I've been using a CPAP regularly for about 3 years. I had what you might call vivid dreams or nightmares off and on even before using a CPAP. I still might have one once in awhile but they aren't as regular and often. Here are a couple of articles on using CPAPs and dreams that I thought you might find interesting and maybe helpful.

Here's an article that has a few things to try that might be helpful.

One of the things mentioned that really has helped me is setting a regular time for going to bed and waking up. Also avoiding coffee and exercise just before going to bed.

I too had nightmares from sleep apnea and I think the CPAP contributed as well.I often woke up out of breath and shaking all over....even with the CPAP.
Knowing the CPAP was needed to live, I tried to wear as much as I could. I dealt with severe sleep apnea for 13 years. I hated it and always was researching another treatments, which many I paid out of pocket without success. Last year, the FDA approved a surgical implant I had been reading about the past several years. It TRULY has saved my life. PLEASE research Inspire Upper Airway Stimulation. It is surgically implanted and is in tune with your breathing NOT apneas. It is so new, many doctors do not even know about it. I share the information with everyone I can. It is only performed now at the countries top hospitals, Emory, Vanderbilt, etc. I had mine done at Duke Medical Center in Durham, NC. They were incredible and my life has been changed. I sleep, my color is better, depression better...a true miracle!!!!! Inspire is the only company I know that makes the implant but are there at the hospital every step of the way. Their website has a wealth of information. They fight for their patients too in obtaining approval from insurance companies.Please check it out!! Good luck!
