We have two kinds of memory, short term and long term. Short term memory has everything you experience, and the most interesting bits are converted to long term memory, and the rest are forgotten. Often a menial task is so boring it doesn’t make it into long term memory, and we wind up with a recent gap we can’t recall. You are fully aware during that time, you just don’t remember anything from it.
