Thread: I was a perpetual invisible lettuce-eating machine?

I wasn't Lucid, so I'm fairly certain this dream belongs here... but this wasn't a "normal" dream persay.

I had already had two non-lucids last night. One was during my initial sleep cycle, the other was after going back to bed from the bathroom.
The third "dream" just consisted of me being half-asleep laying in bed, eating lettuce. I couldn't see or feel the lettuce, nor could I taste it, but I was still putting it into my mouth by wiggling my fingertips. The rest of my body was still. I could chew it and I could hear and feel the chewing, but I didn't, or couldn't, swallow. It would just chew down to nothingness, only to be replaced with more invisi-lettuce. That's it.

I wasn't aware of the dreaming, but I knew I was in my bed, asleep. I wasn't Lucid, but I didn't feel... asleep either. Also I'm pretty sure I wasn't chewing on my hair in my sleep ala "I ate my pillow."

What on earth was this? Some weird sleep-paralysis? Was it just a weird-feeling normal dream? Did I just really really crave lettuce?
