If you really "saw" things within your sight that you know are not physically there, no matter how those visual representation made you feel, you need to go see a doctor, as neglecting it might lead to more serious and even harmful situations.
But if you don't really "see" them and you fully understand and acknowledge them as a manifestation of virtue and well-being you have as a person that your mind made, it's okay.
