Perform ghusl when you wake up before fajr.

If someone have wet dream, he noticed at 1or 2 O’clock, then he slept again, thought he will wake up before fajr then make ghusl & pray. Is this ok? Or he has to make ghusl as soon as he noticed he had wet dreams? Pls remember we r workers if we have to wake up midnight & make ghusl we might not be able to sleep again soon, it will affect our day time work.
