Six explained projecting to Baltar once and it was the Cylons ability to create any view of their surroundings they wanted. They showed Baltar walking through halls of a Baseship when Six said she was walking through a forest because she wanted to. They snapped the camera back and forth between these perspectives. It was clear to me at the time that Cylons can do this at will and its been shown many times that the Colonials can do it under stress, unconsciously or under specific circumstances. Baltar did this from the Mini-Series with Head Six but you mentioned him. Apollo did it also after he was shot down in the Blackbird. He was flouting in space but from his perspective it looked to me (when I watched it later on DVD a few times) like he was projecting that he was flouting in a quarry on a summer day on Caprica. Adama projects every weeding anniversary that he is talking to his deceased wife. People might call this daydreaming but I don’t think so. I think Apollo and Adama have the ability to project and don’t think its anything more than daydreaming. I didn’t think much of Apollo’s episode until Adama’s conversations (then I went back to the DVDs and watched both episodes a few times) with his wife but that hit me like a ton of bricks, slap my face, OH YA, moment. He was not remembering past conversations, he was projecting new ones with his wife. Adama can project at will, one day a year and doesn’t think its more than a daydream and doesn’t know what he’s doing is different than what real humans experience because he has never met one. I think all Colonials can project, they don’t know its different than what we do because there none of us left to see the difference. The Colonials are Cylons, just different S7 and programmed to think they are Humans. I think the FF are probably enhanced copies of earth humans. The chief was shown dreaming once and that looked more like a dream to me than projecting, I’m not sure if the FF can project.
