I don't know about the details of the meaning of the number of prongs, innerlight, but staffs typically represent mystical power.
Questions you might ask yourself are...
In what way do I feel my spiritual power has been lost?
And... what feelings and thoughts was I having that I wanted to hide from my friends?
Or... what did I think would happen if I didn't hide?
To me this dream calls for more self-awareness and self honesty.
p.s. I just noticed this post is from months ago. Probably by now you're dreaming of other things... maybe.
