My daughter can literally sense me walking into the room from her deepest sleep. All the lights are off before I walk in, the door is already ajar and opens silently, the floorboards don't creak and we have super thick carpet, there's white noise playing, the fan is oscillating and I don't make a single sound. There is absolutely no way I somehow do something that could disturb her, and yet this is every night. I'm a good 4-5m away from her as I walk in and on the opposite side of the bed, so how can it be that she knows I'm there?
