Yeah.

I wouldn't leave my door unlocked just so that strangers could come in, just because I'd believe they were here to have a heart to heart talk about life experience with me.

If you don't already have a very specific, trustworthy, and vetted spirit in mind you want to Walk-In, I'd keep the door locked.
