There is a door in this world, to another world.
You can easily pass through this door into the other world.
The catch is that once you have passed into the other world, you will acquire a new identity, new memories, new ideas. You will forget all about the older you. You will think the new you is the older you. You will also forget all about the door.
The most troubling bit about all this is that you may already have walked through that doorway.
There is only one way to tell…no, not really. You’ll never know.
