A couple times now, I fell into a lucid dream and I didn't even know it!

First time, I was laying on the floor (First hint) and my mom came in and said we have enough money for new phones! I was like, ok mom thanks for waking me up for that. Then when I woke up I realised I was lucid.

Last time, was kind of a nightmare. I was actually lucid and getting terrifying thoughs while I was laying. Seeing things in the dark it was quite scary and weird. Pretty mad I didn't realise I was lucid!
