'unreal surroundings' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'creepy scab developed' is the wordplay.
'developed' is an anagram indicator.
'creepy'+'scab'='creepyscab'
'creepyscab' is an anagram of 'CYBERSPACE'.

'in' is the link.

Can you help me to learn more?
