Where am I

Sometimes when I wake up for about 3 seconds I have no idea where I am. Then I realise I am in my bed in my small home near my small family. 

But then I think for a short time, where is this world. I mean we are somewhere in the Universe, but where is here really? Where is the universe itself? Is there more reality beyond the universe? What was before the universe, where does it all come from and where does it all go. Is there a higher level of existence? I don't know.
