I know what you mean, it’s really hard to describe. I have these dream’s from time to time, very rarely actually. Mostly when I had them I was sick and had fever, but not only when sick. Once I got this dream when I didn’t sleep for more than 24h.
I wrote on another topic about this:

I think its not sleep paralysis, it’s not a dream… it some state between dream and waking up I think. It really feels strange almost like if you were dying or like you said… the feeling that something very bad happened and you can’t fix it.
Once I was so confused… when I woke up I was still like dreaming and couldn’t realize what happened and I also needed couple of minutes until I realized that everything was ok.
