I like that! I have those thoughts too, as well. Just never had a solid name to call those times.
I feel like, for me, it's all night and not just for an hour or so. But my greatest ideas and thoughts come at night that keep me up. You have heard some of the work-related thoughts, now if only hive post ideas would pop into my head that easily.
Good post! Nice to hear that you and others in the comments experience this as well.
Lucky for me it doesn't usually keep me up all night. I'd probably be even less personable each day if that were the case!
