'twinkle' is the definition.
(thesaurus)

'gold oddly i'm dreaming about?' is the wordplay.
'oddly' means one should take alternating letters (letters in odd-numbered positions).
'dreaming about?' becomes 'mer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The alternating letters of 'gold' are 'gl'.
'gl'+'im'+'mer'='GLIMMER'

'of' is the link.

Can you help me to learn more?
