I've always felt that I don't belong in this world, is this normal?

I belong to another reality a specific reality i see the ones who live along side me in that reality in my dreams and sometimes in the waking hours i have children there......one due to be born in december........i have people i love very dearly there i have a different life there im a different man there and all i have in this world to remind me of this world is a small pain on my left index finger like a burning ring that reminds me my children are there waiting and that i cant give up yet............ thank you
