I am normally a sceptic when it comes to things like the supernatural, but I have had a similar thing happen to me, or at least that is what I am left to believe. As a child I used to dream I could fly, quite a normal occurrence it later learn in life. But I do remember that I would fly down the stairs and out the front door the and over the house etc. On one occasion I dreamt of flying over the back fence which is tree lined and over the neighbours garden behind it. Well the following day I had an image in head of te neighbours garden which I had never consciously seen and made an effort to find a spot in the house where I could peer into the garden. Imagine my surprise when I found the garden looking the same as my dream! I ask myself though, if I could peer into the garden, maybe I had already done this but forgotten, who knows.
Dreams are quite odd though. Following a serious accident in '95 I was invited by the doctors and nurses of my local hospital's ITU, to a 4 week induced coma. That was an interesting 4 weeks, I can tell you. Completely knocked out I lay in a constant dream state where my subconscious put dream like images and situations to the sounds my ears were actually hearing. Not that I new any different and to this day I have some pretty odd memories of those dreams.
The mind plays some very interesting tricks though take Daja Vu for instance, i've had that several times .
