Mine is a repost from my dream journal. For the duration of the class, I'll make this my journal then move everything there. This is a short bit of several dreams (I can remember dreaming more than once, but this one dominated it).

I woke up at 3:33 to the sound of the TV on in the living room. The living room is about 2 rooms down from the bedroom.

Since I knew I turned it off, I checked my phone for a dream check (no other light in the bed room). The time stayed despite tests, I checked my e-mail, and that stayed too. No changes at all, and when I looked at the e-mail in the morning, still there.

Confused, I went to sleep and had another dream. I woke up again (I want to say it was 4:24), and the TV was still on. I wake up this morning around 5, and the TV is off. The TV can only self-shut off if it's on a blue screen (I've tested this). Clearly, I was dreaming, but why couldn't I tell?
