Bless his heart.

That light sleeping no one ever being able to sneak up on you is a response to trauma. The mind will allow you to sleep deeply only when it truly believes you're safe. Otherwise, it maintains a constant vigil, even when sleeping.

I am the same way.

It's good in some ways, but it's a hard way to live.

It's good that he had you/ his family. It makes life better--makes it worth living even if you don't feel safe.

It's a great comfort to me that my daughter sleeps like a lumpy log, lol.

Much love to him, and to you.

If you are a sound sleeper, send him a big 'thanks' tonight. It's a precious gift to have been made to feel safe.
