This video explains why we are not able to remember our dreams which has to do with rapid-eye movement sleep. We are all pretty good at filtering out things that don't matter, the stream of consciousness when doing something simple such as walking to your car you probably can't recall anything, some scientist think this is what takes place in our dreams(Life Noggin). Things that happen in our consciousness come natural to us, and obviously we don't have to think about. This makes it hard because we are used to a routine and can't recall what went on during it.
This video explains the exact scientific way of how memories are formed in our brains. All of what we come in contact with first lands in short term memory for either a couple seconds or a few minutes, from there it moves to the long term memory through the hippocampus, and lastly to the storage regions across our brain(Catharine Young). Long term potentiation is where our memories are stored being held by synapes. As we age our synapes don't remain as strong therefore causing us to lose memories.
This article explains how if something isn't going to hold our attention it more than likely will not be relevant. What we observe leads us to choose what we think is important and what not for how we live, and is usually related to something being new or fresh ( Shahram Heshmat Ph D). We pass up things that have no relevance to how we live our life's, things that we don't necessarily need to survive, everyday. For example remembering which side you woke up on this morning has no importance therefore your brain thinks 'well why do i need this?' if there is no logical reason it is then thrown out.
This article explains how a tragic experience that brings emotional pain could keep you from remembering something because "bad feelings will make sure that you keep remembering that event" (M.Farouk Radwan, MSc). When something reminds you of an event that brings you emotional pain it keeps you from wanting to remember it. This is also the reason why tragic events seem to never fade. You think that nothing will reach the level of pain you've experienced in the past, therefore nothing will take its place.
The article explains that the way we perceive things through "Sight, hearing, touch, smell, and taste, along with...the environment, all play a role in perception" (Nelson, M. Rae). In this Nelson shows how our scenes and the environment that we're put in have an effect on our memory. We may not be able to remember a situation if the environment we were put in is similar to one we've had in the past. It also shows how the smallest thing such as the smell of something can potentially remind us of a previous situation.
The video titled Why Do You Remember Dumb Stuff But Forget Important Stuff The speaker says "Your brain prioritizes moments or factors presented earlier as they dictate what's to come...Your brain pays very close attention to moments and decisions that lead to positive and negative outcomes." (DNews). With him saying this DNews shows how automatically emphasize events that our brains think are more important than other events. We aren't able to remember certain things because our brains find them irrelevant, and throw the memory out.
