S.H.
Yes its normal.
My girl is 7... and she still occasionally gets scared at night... of just stuff in her imagination. She is a normal kid and normal habits and normal life... we don't expose her to scary stuff outside of her age etc. all the regular stuff.
It is developmental.
Even at that age.
When I was a kid I was like that too.
I grew out of it.
My parents didn't make a big deal of it.
Kids grow out of it.
All the best,
Susan
