Weird dream about time and Youtube?

Last Thursday 3/31 I had this weird dream that I was on youtube looking in the comments section of a video. I don't know what video it was and I was focused on the timestamp of the comments so I couldn't read any of them or I just don't remember them. It wasn't really a timestamp though it was a countdown where the timestamp should be on a comment and it started at 10 seconds. Around 5 seconds I thought "When this gets to 0 it will be 10 am" and sure enough as soon as it hits 0 my alarm goes off which I had set for 10 am sharp. I had been asleep for a whole hour so there was no way I couldn't seen a clock and known what time it was. Any thoughts?
