is it true that it is an ayin hara to sleep facing the door?

Hello, this is a quick question - I see people raise their pinky when the Torah is lifted and then kiss it before putting their finger down. What is the meaning behind that practice and does the pinky stay up the entire time the Torah is raised and only put down once the Torah is covered? Thank you.
