I don't understand how some reality checks are supposed to work. I mean, don't you have to really believe that your finger will go through your hand, or that you will float, for it to happen in your dream? I don't think I can do that. I will always have my doubts as to whether it is a dream or reality.

It seems to me the only reality check of any value is the one where you look at writing then look back.

Can someone please clarify?
