My subconscious seems to enjoy tricking me into thinking I've just woken up. Like, say I set my alarm earlier than usual for an appointment or something. More often than not, I will then have a dream about being awake at that earlier time. And then my alarm goes off for real, and I'm like wait, why am I back in bed? It's kinda like Inception, except instead of my dreams having cool action sequences, they have monumentally boring everyday events in slightly unusual settings.
