At the time, I never gave thought to the possibility of them being 'alive' in some way, and Rob often teases me that they have awareness and feelings, so I just roll my eyes at his sense of humor. However, we have both observed that they seem to have some personality, as they have an intense stare that feels like they can actually see. And they've been caught moving (like rolling over on the bed) without being touched. The first time it happened, Rob & I just laughed because it seemed like coincidence. After awhile, it didn't.
Now we've come to live with the concept that some of our own spirits (Kokoro in Japanese culture) may have begun to inhabit them. I don't tell a lot of people because they'd either believe I'm crazy, or just teasing them for a reaction.
