I went through a period of time where it was necessary to request help to remove an entity that was attacking my lower abdominal area around bedtime. Second chakra area, most likely looking to attach to my chi in this location. It took a few weeks if I recall correctly before it stopped showing up. 

it would always show up as an energetic presence when I’d get into my rack/bed(I was out at sea during this period) and a painful piercing sensation would stab repeatedly into my lower abdominal area. I could watch my abs flex with each “stab.” It was not a great moment for me.
