Hello, 1.The Past Unreal Conditional is used to talk about imaginary situations in the past. You can describe what you would have done differently or how something could have happened differently if circumstances had been different. 1. I would have felt much better spending my time at home. (Past) 2. The Present Unreal Conditional is used to talk about what you would generally do in imaginary situations. 2. I would feel much better spending my time at home. (Present) I hope it helps!
