Magnus studies the branches of the cedar tree about ten yards in front of him. "I guess they're different for everyone. For me, it's like when I had asthma, before I died. Asthma is this thing -- it means you have trouble breathing, for... some reason, and sometimes it flares up into a full-on attack where the symptoms get really bad, really fast. I got a total glow-up when I died, so I don't have asthma anymore, but..." He shrugs. "It's this feeling like I can't breathe -- like something is crushing my chest, and something really terrible is going to happen. Heart racing, I actually feel temperatures, or something like them. When I was a kid, I would have really bad attacks when I was sleeping inside unless my room was totally empty and totally dark. Going outside helped."

It's not a complete explanation, but he doesn't know what else to say. He trusts Lan Wangji to asks the questions he needs.
