My daughter, at age 4 to 5, really believed that if she sat in the lotus position, closed her eyes and breathed "oooommmm" she became invisible. I don't know how she came to this but needless to say I played along with it and would pretend to look for her when she did this. Later on she was disappointed that this didn't work when other people were in the room. I told her her special powers only worked when only mum was in the room because she got these powers through me.
heh heh...
