Do you actually pass out or is this part of your vision? If you are actually passing out I'd seek medical attention.
Otherwise this could honestly mean a wide range of things. It gives me the impression of an Olympus type setting, the home of the Greek Gods.
The sense I get of it is that you're looking to new horizons, ready to expand your awareness and understanding of life in general. Perhaps you're about to start a journey, mental, emotional, or tangible? Maybe you're just moving on in some sort of study?
