You are all that you have experienced.
Our consciousness serves not to gather information but to limit information.
There are many misconceptions about memory. Eidetic memory, total recall, has never been proven to exist; however, there are many savants who have amazing powers of recall. Here is a real shocker though: We never forget anything unless our brains are physically damaged. The human brain is write only, you cannot overwrite memories.
The reason we don’t “recall” everything is a matter of retrieval not information loss. It would be difficult to function if every memory was present at all times. We “forget” to allow our consciousness make sense of things. It is for this reason that we may dream of something we had “forgotten” years ago.
Memories can be triggered by smells, sounds or feeling. Just because these memories are not in the forefront of our conscious minds does not mean they are no longer there. So, be very careful what you place into your vault of memory because memories are permanent and they make you who and what you are.
