I have memories from probably that far back as well. Mine are color, because they often have to do with toys and the colors are visible. Crib time, those infant toys that dangle on strings and squeak when squeezed or bitten, being carried about and bottle fed. (Heh. I wonder if that's what's "wrong" with me.) I have vivid connections between memories and scents, too, which I gather isn't all that unusual.

Do you dream in color or in black and white?
