Thanks Xei ,Yes ,I have often had dreams of being naked and feeling ashamed but never before questioned the reality of it in the dream . What I hope is that my dream-self is beginning to question things more and more ,now that during the day I keep asking myself 'Is anything strange happening ?' 'Would I normally be doing this?' etc.
As well as looking for specific dream signs I want to carry that sceptical attitude into my dreams .
