Have you ever stopped and thought about the incredible number of sensations and experiences you have, even in a single day? Our brains filter out the majority of the information we take in each day, because most of it is unimportant and would only overwhelm us. But even those sensations and thoughts we ARE conscious of in a given moment are rarely committed to memory.  At the end of each day, you can probably recall most major events of the day. Those with better memory might be able to recall many of their feelings and thoughts, and notable sensations (feeling comfortable, cold, in pain, et cetera)… but there are still innumerable experiences that are never recalled.
