On time
Has this happened to you , you really WANT to go somewhere , set the alarm , and wake up about 5 minutes before the alarm actually goes of 
(im not talking about getting no sleep out of excitement here of course 
)
/me wonders
this happens to me ALL THE TIME
Yes happens to me everyone once and a while, and I don’t even really want to go anywhere.
All the time.
When I was younger (teens) I didn’t have to set an alarm clock for school because I knew I could wake myself up on time. I always did set it just in case, but 99% of the time I would wake up less than a minute before it went off.
On a few occasions when I have needed to get up early on weekends, such as bank visits I was always able to wake up within 5minutes of the alarm going off. In all cases it was natural waking, no noise or bodily function requirements.
Now tell em what is wrong with the search engine: https://community.ld4all.com/t/autosuggestion-to-wake-up/26250

I sometimes wake up an hour before my alarm clock and I just go back to sleep. I woke up just a few minutes before my alarm went off too sometimes.
