An evil spirit left the room

When we first moved into our new house, my son who was sleeping in his new bedroom was woken up every night crying as he could not sleep and something was disturbing him in his bedroom. I took the anointed oil from church that was prayed for by the pastors and went into that room anointing it with oil and prayed. Whatever was in that room left and since that night my son was able to sleep with ease!
