Multiple experiences over approximately a two year period. Always right after I fell asleep. There was always a paralysis that I fought. Often there were bluish lights on my ceiling. Most of the experiences ended when I was able to fight off the paralysis. One experience included a puncture in my back which I would equate with a medical instrument. I felt the minor pain of a pinch and had a pimple like mark for a few days. They were always behind me during the encounters. On one occasion they successfully removed me from my home and I was taken aboard a craft that was hovering in the courtyard in front of my house. I remember being placed in a geleatonous cylindrical vat from the bottom. The next thing I remember is waking up in my bed 14 hours later and completely exhausted. The experiences were very frequent until the successful removal from my home. That was October 2012. I have had a few seemingly random infrequent experiences since then.
