Has anyone else had experiences where their dreams have totally changed their perspective ?

So i've been going through a rough time lately. Recently, i've been having a series of very real and lucid dreams which have taken me back to a time when I was happier (blended with a mix of trying to mix it and explain it with current events). I woke up this morning after one of these dreams feeling like i've mentally re-set about 6 years of my life. I know what I want and what i'm going to do to achieve it.

Has anyone else felt like this ?
