Why is it easier to relax in Emma's bedroom than my own?

• She has the perfect white noise machine
• Her room is in a house with other people in it, which makes it feel inherently safe and cozy
• She is often there, so even if I'm just reading or messing around, I don't feel in danger of sudden loneliness
• Lighting
• Her bed is in a "nook," tucked in with walls on three sides
• Fluffy rug
• Window facing the neighbours, sometimes you can hear them
• Soft blankets, lots of pillows, old stuffed animals from my childhood
