Yes, some Starseeds can communicate with extraterrestrial beings or entities from other dimensions. However, many channelers claim they can communicate with extraterrestrials, even if they don’t identify as Starseeds. And many Starseeds receive messages through dreams or meditation without having to practice channeling.
Some channelers may or may not identify as Starseeds that claim to be able to channel various races. These channelers work with different benevolent Starseed races to deliver direct messages to other Starseeds, Lightworkers, and Earth Angels. Often the communication is about energetic updates and progress reports on their missions.
