MEMORIES ARE NOT REALLY CONNECTED.

Water under the bridge. I am not really the I from a moment ago, a day ago, a year ago. You are not you from a moment ago, even though the self (which is a product of memory/thought) is functionally useful, at work, etc. 

"The belief that memories are connected brings the ego to life. This is known as the reification of the ego. Reification means to give reality to something that is not real."
