A father of someone in our church family was having health issues that would cause them to have extreme pain. He was only getting sleep for about 60-90 minutes at a time. One night while having trouble sleeping, his wife covered him with the prayer blanket he had received from our group. He immediately fell asleep and slept for 4 1/2 hours.
There's nothing magical about the blanket, but the prayers that have been prayed for the individual and that are covering him brought comfort.
