Why not question reality, actually?

The most vivid memories one has are usually remembered because they are the most vital experiences engorged with the “realest” feelings. However, memories fade with time—rotten, in fact, over time if not relived. Sometimes these blurred memories may even allow the thinker to doubt, if skeptical enough, the realness of these memories, moreover, the activities engaged in the memories. How can one persist to feel real about the memories when they become so abstract and dreamlike, which consequently brings in the following question of, how shall one remain faithful to these feelings and experiences that once felt real, in the forsaken form of decayed memories? 

What is the reason not to be so skeptical of the epistemology of the events that our memories carry? You could be dreaming this very moment and you wouldn’t even be able to know it. Something can easily be remembered as realistic events when it has never happened, and episodes of reality often occur without one’s awareness, thought-process, thus not to even expect it to make its way to the hippocampus. Reality happens in our everyday’s business and when we are asleep... or does it? Until time machine is invented, how is one able to prove the happening of something, realistically? You just can’t. 

Amnesia is a real thing. People lose memories; sometimes of proximal knowledge, sometimes—eventually for some—everything. Names, identities, moments, achievements, knowledge, meanings... How are those surrounding the forgetters supposed to define what’s real? What is real to the forgetters, then? Because for all they know, the achievements and families that they are informed to have built certainly don’t exist. “Nope, never even heard of it.”

So why is philosophy of epistemology regarded as silly and pointless by some people? Have they not once felt real and more sure than ever about something and then losing that grip of sureness? Does it actually mean anything to be certain about something? Maybe, at the moment. When people make vows, promises, oaths, and all these words to describe the gesture of guaranteeing something, either about the past or the future, they still swear by the moment. Forever perhaps only lives in the moment, when the very word is said, or when one is completely and entirely sure about what they are feeling—when they are feeling the realest feelings.
