My latest lucid dream was just standard until I accidentally entered some other dimension.

Let me explain.

I was in the middle of some sort of field when I became lucid. The dream nearly collapsed, but I took a deep breath and relaxed, and the dream cleared up. I took off and flew over a river, when I curved upwards so I could fly into space. Instead, I broke through the sky into some alternate night version of where I just was, but with a pickup and a stunningly beautiful sky.
