, x-ray
a. electromagnetic radiation emitted when matter is bombarded with fast electrons. X-rays have wavelengths shorter than that of ultraviolet radiation, that is less than about 1 × 10--8 metres. They extend to indefinitely short wavelengths, but below about 1 × 10--11 metres they are often called gamma radiation
b. (as modifier): X-ray astronomy
2. a picture produced by exposing photographic film to X-rays: used in medicine as a diagnostic aid as parts of the body, such as bones, absorb X-rays and so appear as opaque areas on the picture

What does it mean when you dream about an X-ray?

Being X-rayed in a dream may signal wanting to see through a situation or the intentions of someone who is emotionally significant in one’s life.


Dreaming about getting an X-ray or looking at an x-ray may not have anything to do with health matters. This dream suggests that you are ready to look beneath the surface of a current situation or problem. X-rays require focused energy and your dream may be a reflection on the energy that you already possess. This energy will assist you in gaining insight and awareness or help you with problem solving. Old dream interpretation books say that dreaming of X-rays is a dream of the contrary. That is, you will be released from your worries and enjoy good health.
