before we were three

this piece in Psychology Today, rather spookily illustrated with a picture of a staircase, was brought to my attention by Norm, for which thanks.  It indicates that while most of us remember hardly anything from before we were about three, young children have memories that go back further, but they lose the ability to recall those memories as they get older.  This appears not to be the same syndrome as in older adults,  whose memory changes too, but for short-term events, and it also appears not to be to do with the ability to put memory into words.  I always thought it was, and that I couldn't remember much other than certain visual images from before that age because I didn't know the words for those events at the time, but apparently I was wrong.  A recurrent nightmare I have had, of soft walls pressing in on me and making me feel I am suffocating, is I believe a memory of my own birth, and recurs as a nightmare because that is the only way my brain can process it.  And, which concurs with the Psychology today piece, I used to have this nightmare A Lot when I was a child, and the frequency of it has steadily diminished over the years.  It is several years since I have had it at all.  I am not alone in having that kind of (bad) dream, others have told me of very similar dreams.  It occurs to me to wonder if those born by Caesarian section have that dream.  And to mention in passing that babies born by Caesarian are much prettier (perfectly round heads and flawless skin) than others are.  Just musing...
