Does anyone else get detailed blissfully happy dreams once in a while?

About every two weeks, I have these incredibly vivid, long and blissfully happy dreams that have zero connection to my real life. I wake up absolutely euphoric, like I’ve been pumped full of endorphins.

In reality, though, I’m very severe, bedridden and, therefore, I’m emotionally flat and numb from the physical toll. It’s kinda weird that my brain conjures these escapes. Is this its way of coping with harsh reality?
