Dream about having some means of destruction (5)
I believe the answer is:
armed
'some means of destruction' is the definition.
I can't tell whether this defines the answer.
'dream about' is the wordplay.
'about' indicates anagramming the letters.
'dream' is an anagram of 'ARMED'.
'having' is the link.
Can you help me to learn more?
(Other definitions for armed that I've seen before include "with Browning?" , "Gave weapon" , "Provided with weapons" , "Given weapons" , "prepared to shoot?" .)
