I have a lot of pre-school memories. I wouldn't know how to pick just one. I remember wandering around the house alone when my grandmother was taking a nap. I remember jumping on my bed and talking to my imaginary playmates (Tommy and Lisa). You want to know something really deep, and maybe even gross? I remember having nightmares when I was three or four that I was being suffocated by what I thought of as raw hamburger (I think I actually have trauma memories of being born, looking back on those nightmares).
