I have; It really depends on where your consciousness goes. For example, in one instance I was looking down at myself - I was aware of the environment around me, the air quality, temperature, ect... but not by means of a physical body which I could not feel. Those things around me I just had a knowing of and though my focus was downward to the point of not being aware otherwise, my vision was not limited to any particular direction. This was not simply an out of body experience either as their was a temporal component. I saw my myself be accidentally tripped which caused me to fall down the stairs. When I came to I was able to catch myself and avoid the outcome.
