What is a drop earring? Sorry, I don't know. What is it you are wanting? To wear a symbol to show that you look beyond the physical? I am not sure. Most symbols go with belief systems. I am not sure of one that is associated with astral projection. Maybe someone else will know. You could probably find something that represents a chakra, but I do not know if you are into energy work. Just get a shirt that says, "I would rather be Astral Projecting". [:)]
I didnt find other word from dictionary. Drop earring is a symbol on a rope around your neck.
http://www.hot.ee/valgusesaar/smaragdtahvlid%20sissejuhatus.htm (smaragdtablets) mabye this symbol, made of triangles. For me it reminds tesseract (4Dimensional cube. cube x cube = cube\2 ) here we can see triangle x triangle.
For me this symbol represents higher dimensions.
I would like to wear on my chest somekind of drop earring what shows that i am man who knows he has got his spirit, or the one who shows i am astral projector.
I am asking becouse i dont want to wear simply a cross, becouse i am not a christian.
