The weird thing I've noticed about this is that it takes me a shorter time to re-orient myself when I'm sleeping in a "strange" bed to when I'm sleeping in my own. If I'm in a hotel, or visiting family or house sitting, I'll wake up with that "where I am I?" feeling, then almost immediately remember I'm not in my own bed and I'm not supposed to be. "Oh, yeah, I'm in a hotel somewhere."
And I'm good then. I can quite happily get on with sleeping in an unfamiliar bed.
But when I'm in my own bed, in my own house, I still wake up in the middle of the night with the "where am I?" feeling, but it takes a while for the pieces to click into place that I'm where I should expect to be.
I don't know why this is, but it's something that has followed me around for a few years, and from house to house. Wherever it is that is actually "home", that's the place where I take the longest time to realise where I am.
