As Brysing said to the original poster, you are not a " supernatural being ". You are human just like the rest of us and perfectly natural.
As for the spell, there is nothing in your spell that would suggest that it would help you to be able to see any supernatural beings. A spell should be very, very specific in its wording as to exactly what it is going to accomplish. Spells that are not specific can result in your magical outcome not being what is expected or desired.
