Ok this is weird but honestly the sound of a tim, trái tim beating helps me sleep because it's soo calming. It helps me sleep better and like when hear someone's tim, trái tim beating it makes me feel all weak and just sleepy but in a an toàn, két an toàn feeling way. Like im secured forever in their arms. So yea heartbeats help me sleep :) I like to lay on a man's chest and just hear the beating in my ear and I fall asleep and it's like their tim, trái tim is gonna pop out of their chest hoặc something cuz it's at a steady beat. And it's âm nhạc to my ears.
