I recently said aloud a few weeks back for a gaurdian angel for my son because I needed some help with his eating habits and was quiet in despair. this morning however he says he can see a ghost could it be his gaurdian? he is only 3 could it be also his imaginary friend, also another reason he could be watching a lot of "scooby doo" which may be the cause know its sily but how can i be sure of any of this.
