also i wanna remind people how important their memories are, your personality the shape of your soul etc gets created according to the experiences/memories/information you have, everything has memory/information and can store new memories/information, to lose your memories/information is to start from scratch again, imagine a beatiful statue it took you years to build and suddenly it collapses to dust. also there's an old saying "those who forget their history/ancient memories are condemned to repeat it"
and now that our solar system is under alien occupation the past 13,500 years the last thing you wanna do is to erase your memories cause you'll never figure out how to break free from this solar system your soul will remain here for as long they want exploit you in every way that serves them.
google "cancerous entrapped reincarnation" for more info.

thanks to the replies of this thread i learned about a tv show "dollhouse" that is all about the technology of memory erasing and how you can control humans with it precisely like robots. Our owners love to put the truth in our face and not being able to see it, it shows them how effective their brainwashing and programming is and that we have no common sense left in us.
