You’re not “supposed to be” feeling anything in particular. When people ask me this, especially those new to Reiki, I tell them some of the things my clients have told me they felt after a Reiki session, but I always emphasize that people are different. If you don’t feel a warm sensation or see colours during the session it doesn’t mean that something went wrong.
I was fortunate that I was able to feel the energy in my hands when doing Reiki right from the beginning. It helped me get past my inner skeptic because I wasn’t having to just believe what others were telling me. I had a direct experience of it.
However, for whatever reason when I was the one receiving in Reiki sessions, I didn’t feel a thing for a very long time. I have no idea why. Maybe I just wasn’t as sensitive to the energy in the rest of my body as I was in my hands. Maybe my inner skeptic was sabotaging me somehow. Maybe I was expecting something dramatic and missed more subtle sensations. I can’t say for sure.
But even though I didn’t feel anything during the session, I did notice subtle things afterwards. Clarity and a quietening of thought and a general “chill” feeling were the first ones for me. These, and the feeling I had in my hands when doing Reiki, encouraged me to keep at it. And now I do feel different sensations when I am the receiver, but not every single sensation that people have told me they felt. Again, everyone is different.
So don’t worry about feeling specific things that you’ve heard others have felt during their session. Just relax and see how you feel during your session and in the hours and days afterwards.
