I am in the grounds of a school, there’s a huge statue with a hidden switch in the base that opens a doorway. When I go in, I see that it’s smaller on the outside.
The door closes behind me and I describe to people outside what I can see. They can hear me through the wall. There’s a whole alternate reality here. I step out into it and explore. I realise things are different here. In my head is a message telling me to stop the plague in Prague. Even if I have to invent time travel to do this, I must do it.
