Lucid Dreaming and OBE Discussion Board

Is the people stable in the phase? I mean, if I'm talking with someone in the phase, could he become another person during the conversation?

Also I know that if I look something for several seconds, It will change in shape or colour, but what if I look someone's face in the phase? will it be the same? How can I have a complete conversation with someone in the phase without this risks? 

Usually there is no such problems in a full-fledged phase. Persons are stable.
