Until recently, for the star races, to hybridize with humans, it was sufficient to get the person's permission on the soul level. Since 2014, for all hybridizations, it is required for a human to consciously agree in writing or vocally. You are now invited to apply to specific hybridisation programs. The details are available at HumanColony.org.
Humans can now offer their DNA and donate it to produce hybrid children in alien cultures. Pairs of people can donate their DNA to produce hybrid children in alien cultures. These children are born and brought up by alien parents and have a mix of DNA of several human and alien donors. The hybrids created this way live a fulfilled life in the 4th density and as they grow up, often volunteer to help the Earth. Since they are related to us, they will be among the first to come to Earth in person, once Open Contact will occur. The donors have their star children visit them in their dreams. They visit their children in other words in their dreams and speak to them via channelers. The children usually request their parents give them names.
Humans now request and obtain small infusions of alien DNA in their physical bodies. Typically Lyran, Pleiadian and Yahyel infusions are requested. Such upgrades happen gradually spanning months and are experienced primarily on a spiritual level.
