Sometimes we miss things that in the past have known was there, or we just doesn't register our enviroment because there is an intense inner turmoil happening which results in missing time or we are so distracted that we just "don't see". A lot of time we are so inner involved and walking in a trance that life is a blank. Sometimes I can be so involved in my thoughts that I do things without noticing that I am. Best I can say hun.
