In life we may not remember every bit of what has happened in the past but there are major events that get implanted in one’s memory, yes. The very nice events may be the things that you can remember when you were very young. For others the memories may be if you were very hungry, there was no food, because that also gets ingrained into your being. Some major challenges in life are the ones that we remember and the great successes. Not the in between, whether you slept or woke up, the fact is because we do them daily, we won’t remember them.
