When I was young, I did not have my own room. I shared it with a group of siblings, an aunt and I was passed around as a child, so sometimes I am at a large room with grand parents and my sister, and sometimes I was in the living room with mattresses on the floor shared with a bunch of cousins.

I am actually not too keen in experiencing such a thing once more, even in a waking dream.

Just recently. A room where I was in the top bunk. Seemed to be either dusk or first light. I have an aunt still living and asked her. She said the first place my parents lived, before they bought the house was that bedroom.

I could even hear and smell the car repair place behind the apartment because the window was open. Lasted just a few seconds but in vivid detail. For a moment the sheets were those sheets.

I used to solve complicated homework problems back in the day in those not quite asleep and not awake moments too.

...that he thought it's possible that we live a different life every day. When we wake up, we're in another reality that "they" have made, along with all the memories.

Maybe you WERE in your childhood room for a short time.

PS: My dentist is a little strange but damn good!
