Same as Real Conditional sentences, Unreal Conditional sentences are saying that you think an action will happen if another action happens.
The Present Unreal Conditional is used to talk about your actions in unreal situations. These situations are imaginary actions.
In the Present Unreal Conditional, always use "if" and "were."
When you are discussing imaginary situations "when" cannot be used.

3. If I were blonde, life would be easier.
