First of all, I love this story and I espcially love "my brain was squeezing itself." Answers:
- Because the character is such as sound sleeper.
- Embraced herself because she felt a chill and closed the window.
3 & 4. The character was having an out of body experience and was able to see her own body on the bed. Maybe she died in her sleep. Maybe her heart stopped beating for a short time but was put back into her body so she wouldn't die.
This has happened to me.
Great Deb! Thank you~!!! ^^
