I have felt the energy many times, and so have people I have given Reiki to. Last week I gave Reiki to a lady who has a back bad after falling down the stairs. She said that she could feel warm energy going down her spine.
Funnily enough, on that same afternoon, she bought a ticket for a draw and I was asked to pull out the winning ticket, I pulled out a ticket, and it turned out to be the same lady. She won a small prize, and selected some kitchen rolls and kitchen cleaner. She said that she had just been thinking that she had to go to the shops to buy some kitchen roll, and now she didn’t have to it was there in front of her. What a coincidence!
