Yeah It obviously has to be altered from the movie... instead of making sure it works I just check to make sure I have it and that it's spelled "right". The checking isnt necessarily done to see if the totem is real, but if it is there.

Actually I had my fourth LD a few nights ago after changing my sleep routine. Instead of wearing my totem to bed I took it off just before I fell asleep... I dont know if that rose my awareness or not.... so it works in more ways than one i suppose. It's also a snazzy necklace anyway.
