I still have this happen quite frequently when I'm mentally working through a tough programming problem, especially if that problem involves a lot of moving parts. It's like my mind is organizing its understanding of the problem during a dream, so I get bits and pieces of it. Sometimes this leads to useful insights, but much more often I think I've solved some problem in my dream, only to wake up and immediately realize that the solution makes no sense at all. Once I do wake up though, I find that if I give myself a moment to rest and then come at the problem again, I can re-contextualize much more quickly and make quick work of the issue.
