Kind of projection (6)
I believe the answer is:
astral
'kind of projection' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for astral that I've seen before include "like a star" , "To do with stars on altars" , "Resembling the stars - of the spirit world" , "Starry sort of altars." , "Pertaining to the stars" .)
