I agree sounds like the Zeta Reticulans or Grays as others have said. Malevolent beings. Not good. They are the one who abductees say cause the abductions and more for multiple purposes but one of the more popular themes is apparently for reproduction in order to carry on their race because they are a dieing race and some believe they are another version of humanity in another reality or us in the future and a reality that we could turn out or are at the moment due to the way humanity is in some ways in terms of having no heart at times, cold at times and other emotionless or insensitive things we do...HARD to explain but these are the ideas of those who say they have been abducted and told these things by them.
