When we talk about unreal past, do we mean the use only of past simple/continuous to describe an imaginary/hypothetical situation? For instance:
• Supposing I gave you my permission, would you go?
• Supposing I had given you my permission, would you have gone?
In the first sentence unreal past is used. But in the second one?
I don't think the second one describes a past action, but an imaginary, past action. So, are the verbs in both of the sentences in unreal past?
