Last night I dreamt about escaping hostage takers in a big building. When I woke up I realised it was the same big building where I previously dreamt I worked and had to find a printer. And also the building where I dreamt I was at school and needed to find a toilet.
So my brain has built a single set as the backdrop to any dream involving a large area. And bizarrely I don't think it's an actual real life place, I don't recognise it.
This struck me as a bit odd. Do you have regular fictional venues for dreams??
