Suspecting I'm a schizophrenic foreigner

I was living again with an old neighbor. One of my nieces was coming to stay with us, we had to clean the apartment quickly, most of the mess was my roommate's. My niece never showed up.

Our apartment was at the top of a huge bike ramp, I took off on a ride with a group of people I didn't know. I rode by myself into a house of a stranger hosting a family party. The woman, somewhat older than me was angered that I would show up at her party as there was bad blood between me and her family, but I had never met this woman before. She called her attractive daughter over to show her that I had the gall to come to the party. When I tried to explain I had no idea who they were, I discovered I was speaking in a British accent. I became confused and thought perhaps I wasn't the person I thought I was and maybe the lady was right - I did know them.

I left, again on the bike, and was then with my family. I found I was speaking in an East European accent. I unsuccessfully tried to explain what had happened. A single page of a newspaper blew into my hands. I told my family that this was a message to me that would perhaps explain everything, then realized and remarked that I was acting and perhaps was schizophrenic.

Our family went sledding in a parking ramp. I saw a group of people tethered together walking among the highest branches of a gigantic tree and thought of an invention that could grasp three branches at once which would make the activity easier and safer.
