I too don't believe that Flowofmysoul was talking about dream within dreams, what I was trying to say was that I don't quite agree with when you said
but you really are dreaming one dream at a time
because of that thread and how I too have experienced what seems to be several dreams running simultaneously. My bad, in terms of communicating what I meant.

But you are absolutely right, things are not what they seem to be, and when we expect to enter a "new dream" we will most likely have the experience of entering one. I guess in the end what matters is the experience and how they affect us. Thanks for your thoughts =)
