have similar visual memories from a very early age - I remember two (not too specific) scenes from the house I grew up in, when it was being built (no wallpapers, stairs were simple concrete and not yet with handrail etc). The trouble is, we moved into that house when I was ~18 months old, so I "visited" the construction site with what, 16, 17 months of age? It is hard to believe even for me that I remember images from that time, but my parents clearly never "told" me how it looked. I am not sure what to make of these memories myself, but I have them.
