I have been doing regular self-inquiry practice for a couple of months now. In several sessions, there was a loss of self-identity as all identification/attachment to thoughts dissipated and awareness withdrew inward to an alert but very silent, subjective state. In one instance, confusion then arose as to who I was: an amnesic blank was drawn as to what my family background was and who my siblings were. There was no ability to immediately recall it and I literally had to wait about 20 seconds for the mind to come up with the answer. Just one trippy experience that needs to be moved on from, but it shows the power of asking "Who am I?" and getting the mind quiet/withdrawing awareness back into its source. "You" will literally fade out of view.
