If you spoke to Peter and he tells the truth, then Paul is the liar.
If you spoke to Peter and he lies, then it is Paul that tells the truth, contradicting the speaker. It cannot be both telling the truth. Therefore the prior supposition is the correct one.
The person you asked then has to be Peter telling the truth.

If you aren't seeing Heaven while you dream, you're doing something wrong.
Dreams allow escape from the passage of Time.
The ultimate activity is the Dream.
