Hello clearhit: Sometimes I wake up in the middle of the night & I feel so nervous I cannot stay in bed or go back to sleep. I get up & do walking meditation for an hour or so. I walk slowly throughout the dark & quiet house focusing light attention on each foot as it touches the floor. Thoughts come-&-go. I don't try to prevent them from coming up, but I don't dwell on them either. I simply let them fade away at their own pace. Typically after an hour or so of this, I'm able to go back to bed & get back to sleep.
