They seem more like young adults, not children. well with how i see it, the tenno channels their energy into the warframe, and they do it by daydreaming. We wouldn't have known from the start because the tenno that controls the warframes you play as is dreaming, they don't know they who they are and believe to be the thing they are controlling.

Up until this quest of course, in which your tenno learns to control the warframe while awake, most likely by daydreaming.
