Ghosting is a phenomenon that is observed if there is strong light directly incident on the lens and it reflects off the various lens elements, the diaphragms and even the sensor, and causes multiple translucent artefacts to be created. This often causes the photo quality to degrade. One of the ways past this is to use a lens hood, or to use polarizer filters.
The above photo shows examples of ghosting.
Tell me, how do you deal with this?
