I'm sorry to disagree Flobadob but you're wrong.
The average human spends a third of their life asleep! That's 8 hours a day, 4 months asleep every year, 4 years asleep every 12 years, and about 25 years asleep in a lifetime! Except for the occasional dream you don't remember your sleep. Also - most adults don't remember much of their childhood, especially infancy. So, we only remember a small percentage of our lives at all!
I write a diary every night detailing what I've done that day. When I look back over the years I'm amazed how many things I've forgotten doing. Even going places and meeting people are forgotten.
I also have terrible insomnia and usually only sleep three hours a night. The doctors have tried to get me to take sleeping pills but my response is that there are so many more things I do in the extra time than other people who are asleep. I'm restoring my car at the moment (new panels, interior etc) and I'll do most of that in the early hours. I tell the doctors I'll get all the sleep I need when I'm six feet under - I might as well make the most of it while I can!
