      Hi GregShar123 this is a really interesting question. When you drift off to sleep there is a transitional period called ‘stage 1 sleep’ (not a hugely imaginative name, but I didn’t name it). It typically lasts around 10-15 minutes. As you drift off parts of your brain will start to change gears, and do different things. The areas responsible for memory will start talking to each other more and swapping information. As such remembering new things is no longer a priority! This includes the moment you drifted off.
