If I were not an internet stranger, I would suggest you were trying to avoid sharing your experience.

But I will be kind.

I was at my desk, at work, when everything around me changed. I was still sitting at a desk, but it was grand, stately. I was reading a stack of charters, I clearly remember that was the title of the document in hand. The room was richly furnished, but the stone masonry leads me to believe it was a castle.

Now it is your turn.
