This weekend I did a metaphysical fair called the Body Mind Spirit Celebration. I'm pretty conscious of my energy and put a protection field on myself everyday, yet there was an energy that still stuck to me. I encountered a person from a past life that triggered a trauma, giving me pain in my lower back for awhile. Story is in the LIVE post on Facebook.
If you are a highly sensitive person like I am, I really encourage you to get clearings regularly.
