Burying memories deeper into your mind because your subcouncious can't deal with it seems possible, buts it's always there, but your brain can forget things it doesn't need, and if you look at the power of the human mind and body, some people can actually slow their heart, and buddhists reaching enlightment I imagine were like, going into OBEs and LDing or whatever when they meditated, plus people who can through meditation stand on a little box so their feet dont get wed, in a tub of ice cubes covered to their neck, keep their body at 98.6 unvarying through meditation and breathing techniques. So if you had the kind of control over your mind that monks spend 70 or 80 years to achieve to a certain level, you might just be able to erase memories you determined that your mind didn't need. Makes you think huh?
