'Don't Start, Join In!'

I had this dream/nightmare several years ago. This is the oldest dream I remember, and considering my terrible memory I'm quite surprised I still can.
Well, we started off at our house. We got into the car, and I asked where we were going. My mum said we were going to go to Scotland. (We live in England ;D) For the first part of the journey, everything was normal. My brother was annoying me and I was eating sweets. By the time we got to the petrol station halfway there, we were in a videogame. Everything was dusty. (I thought that there was a desert between every country.) When we continued our journey, everything slowly became normal again, until I saw a sign that pointed upwards and said 'Scotland'. Up ahead I saw a hill, and barriers on either side. The barrier had a random pattern of love hearts and other random characters. The hill was completely vertical, and I was scared. We had to go over 100 mph or we wouldn't make it to the top. I got scared that I would fall out of my seatbelt, smash the window and fall to the ground, and in the end that's what happened. It was a long fall and I guess I must have I died.
