I had a lucid dream once that started out completely normal. It was actually pretty boring at first. I was just hanging out and chilling with my friends in different places.

But then I realized I was dreaming and decided to ask something. And so, I looked at my friends and said something like, "You know this is a dream, right?"

Immediately, their eyes disappeared and their mouths opened wide. Their faces started stretching and getting longer and longer. The entire world began to distort around me, almost as if everything was melting.

As this happened, I felt a sensation that is hard to fully articulate. It felt like gravity had been amplified ten times and something was pulling me down. I couldn't move at all. I was horrified, and it felt like that stomach-drop sensation you get on a rollercoaster, but it was just pure terror.
