This a term used to describe someone who is here to wake up to their truth and then share it with others. As far as I have come to understand, lightworkers are people who have an advanced Soul. The same as what you would consider an "Old Soul or Enlightened". Your Soul has had many, many incarnations here and usually other places, and planets as well. The reasons for being here on planet earth varies, however for the most part your Soul specifically chooses a time and life when the ability to remain connected to the spirit realm never goes away. As children we all have the ability to connect with the unseen world, which is how a 2 year old can see grandma who passed away, and it's why the "imaginary" friends are so real to children. A lightworker maintains this connection and this connection gives them the ability to remember everything they as a Soul has learned like skills, talents, knowledge, and abilities. Which explains why a lightworker is very intelligent and talented beyond their years.  This connection also allows them to view the world through the eyes of their Soul. This gives them the ability to tap into a deep inner knowing about people, situations, and the world around them that often goes unnoticed by others. They also have abilities that go beyond the human's 5 senses. Unfortunately most lightworkers grow up not understanding why they are different, and for the sake of being accepted and not come across as wierdos or crazy they shut down their true self and try to blend in with family, friends, and society. However the more they try to run from who they are and why they are here the amount of difficulty and emotional pain increases until they choose to find answers and start the process of remembering.
