Although I have read many dream type books the one that helped me most to understand dreams like the one you describe Kevin was Sylvia's Book of Dreams.
I agree with Carrie what you describe does sound like astral travels. In paticular since you are aware that your flying, have gone through the ceiling or window etc and it feels normal to do so plus they are so vivid. The fact you are noticing things that seem "off" leans toward lucid however, so maybe during astral travel your dream becomes "lucid"? Here are few excerpts from her book that may help you to determine if the dreams your having are in fact "lucid" or actually "astral travel".
Sorry but this post will be on the long side.
Lucid Dreaming (from SB's book of Dreams)
"When you realize during your dream that you're actually dreaming, you're having what's called a lucid dream." "Nine times out of ten, what causes a dream to become lucid is the sudden conscious realization that something in it is too unlikely or downright impossible to really be happening."
After giving examples of lucid dreams (submitted), she also explains that it makes perfectly logical sense to her (based on years of research and study including the works of others who have also studied dreams) that "when it consciously occurs to us that we're dreaming, we can realize that in dreams we can do anything and everything we want with absolutely no consequences, the possibilites are endless. Now that sounds good to me.
Astral Travel (from SB's book of dreams)
"We're born knowing how to astrally travel, we routinely travel astrally while we sleep (an average of two or three times a week, in fact), and it's astral travel that lies at the core of our most vivid and memorable "dreams".
"There is no limit to the people and places we can see, and do see, during astral travel."
"Anytime you dream that you're flying without benefit of an airplane, you're astrally traveling." After sharing ane example (from many she recieved) she goes on to say "astral travel during sleep includes the realization of flying. It's very common, so I hope those of you who experience it don't feel there's something strange or crazy about you." So no Kevin you're not crazy. =) Some people like Sylvia don't have flying dreams but that doesn't mean you don't take astral trips (she does regularly).
"All astral travel "dreams" unfold in a logical sequence of events, just as waking experiences do, rahter than a haphazard jumble of images, people, and locations." There are also always in color.
"Not all astral trips during sleep are prophetic, but all prophetic "dreams" are really astral trips." We go to the Hall of records and read charts which gives us the info. We usually don't recall reading them just what we read.
I too have had night dreams where I'm out in the sky and see the stars that appear much more vivid. I realized I was out there and flying and wondered where everyone else was, that is why wasn't I seeing others flying out of body out here as I was. I have had prophetic dreams as well, of which sadly some have even been of a tragic event (non personal). I have also had dreams where I knew I was dreaming that I now believe were lucid dreams. I often have flying dreams and some where I'm floating rather then flying. It's a bit weird to find yourself floating and you look down to see yourself sleeping in your bed.
Dreams are quite amazing really, and far more helpful then we may think. Keeping a journal has not only helped me remember them regularly but also with understanding what type of dream it was. You never know Kevin those dreams you pass off as coincidence may very well not be? Keep a journal it can it help you with those dreams plus the ones you have shared here. =)
