In any Islamic month. The first Friday night (night between Thursday and Friday) of that month. Take a bath after Esha Salah and wear clean clothes. Then read this Darood/Salawat 10,000 times
"Allah huma salle ala sayyedina muhammade nin nabi yil ummiye wa aale hi wa barik va sallim"
Then 1000 times Sura Kausar.
After that while reading the same darood/Salawat sleep the way the Prophet (Sallal laho alihey wa aalehi wasallam) used to sleep. Meaning your face, facing the kaba and on your right side. Please check in your area how they bury the dead people. Sleep like that in the same direction. Inshallah you will see the Prophet (Sallal laho alihey wa aalehi wasallam).
