I was listening to "Coast To Coast AM" recently. A guest, named Jason, claimed that in his past life he was a horse. He finds being in his human body to be strange to this day and feels he is more horse inside than human. I thought about this reincarnation angle in regards to Raf. Maybe Raf understands what Bumblebee is saying because in a recent past life he was a Transformer and is subconsciously channeling his past life knowledge and experience? Who knows.
