Waking up remembering old songs. Is it normal/common?

Through the years I would wake up remembering old songs which I don't usually listen to. It kinda just plays in my head the second i wake up, down to the exact tune and lyrics too. It could be songs from childhood tv shows, or songs popular 10-20 years ago. Including songs and genres I don't listen to by choice or regularly back then

I tried googling for answers years back but never found anything. I'm writing this post because I just woke up to another og song and figured it's worth a try to ask Reddit for answers.

So does anyone else experiences this too? is there a name for this type of phenomenon?

(btw the og song was Afrojack - As your friend)
