So twice now, I've had these lucid dreams within dreams.

One of them was pretty vivid. I remember dream-going to sleep, and then waking up and becoming lucid. I was fighting spiders and jumping around, but I woke up in my lucid dream, and returned back to my dream.

For my other one, I remember falling asleep in my dream and the lucid dream in my dream seemed really hazy. Right when I realized I was dreaming everything started to fall apart and cracks formed, and I woke up in my dream. A little later I woke up in real life.

I don't really think these are lucids. I wasn't really conscious of them, but I think my dreamself was. I don't know.
