Disoriented
'disoriented' is the definition.
(I know that disoriented can be written as lost)
This is the entire clue.
(Other definitions for lost that I've seen before include "Missing" , "Mislaid or was defeated" , "Unable to be found" , "TV series!" , "confused" .)
(Other definitions for out of it that I've seen before include "Without a chance" , "Eliminated" , "is not included" , "Forlorn" , "unaware of what's going on" .)
