I think I may have heard my Dream Guide once, when I was dozing off early one morning. I was either fully asleep or just about to fall asleep, when I heard a female voice say "Origami, time to get up". I woke up there, and noticed it was my usual time to get up for school.

Definitely wasn't anyone in my house, as only my mother could sound like that, but she was downstairs, and anyway never shouts up to me to get up.
