I believe I was abducted by aliens in my sleep, and they were using something to clean my body.

I was sleeping and in that sleep I was eating poison chips, made from poisonous animals... I started shaking, and lied on my fiancee in that sleeping alien abduction experience, because I started shaking uncontrollably as if I was vibrating... They were using something to clean my body or something or to shape it... I said my head my head and one of the aliens said something about going to my head and I could them cleaning me, and they wanted to transfer my body into another body it seemed but I fought against it because I didn't want to leave my fiancee... The aliens stopped, and mentioned a branch in the Intelligence Community, and said we'll be back which I trust them to do so if the extraterrestrials do come back... They took very good care of me, and I just had to focus on getting my vision back in that extraterrestrial sleeping experience... I felt no pain... And the UFO inside was the shape of the outer layer of my brain with a beautiful bluish white light And when I had gotten up I woke up my fiancee whom is a light sleeper to ask her if I was shaking and she said no... She knows nothing of the experience...
