I was praying a few years back at night in my room with the computer on the browser. Well I had whispering sounds coming from the room . Nobody was there but me. I thought it must be fallen angels to trick. So I covered the Blood of Christ over it. But it kept happening. So I asked The Lord what is it I am being shown here. The St Gertrude prayer for purgatory came up on my browser. I prayed it several times. I never heard the sounds like that again. I pray this prayer at more times now.
Eternal Father, I offer Thee the Most Precious Blood of Thy Divine Son, Jesus, in union with the Masses said throughout the world today, for all the Holy Souls in Purgatory, for sinners everywhere, for sinners in the Universal Church, those in my own home and within my family. Amen.
