How do your dreams end?

[Blue]

Usually, if it's a good dream either it simply fades, or something in reality (phone, having to pee, etc...) interrupts the dream. Most of my nightmares lead to horrible death or injury but, I wake up right before that actually happens in the nightmare.

Of late, physically cold feet have awakened me twice, and a lot of simply waking at odd hours, dreaming, having a night mare or just sleeping. What's with 3:23-3:28 AM? (Central)
