Sounds similar to the times when I fainted. Your timeline is snipped and cut together, without it really "feeling" off. It's like you press a button and you're suddenly X minutes further in time, like someone switching from a red LED to a blue LED by flicking a light switch.

The non-existence of time isn't at all like a dream, or (probably) a coma. It's not like a PC going into hibernation mode and getting time to record what is happening and to do restoration bookkeeping on startup. No, it's as if the time never existed.

Very difficult to explain as most portrayals in media make it look like "a deep slumber" while that couldn't be further from what the experience is like.
