Has anyone experienced a simple, easy way to keep your bedroom an astral no-go area? I'm talking about people (living) who consciously or unconsciously visit in astral, with good intent and otherwise.

There's a lot of information on the internet, including this site, about getting you astrally mobile and remote viewing, but very little I can find on maintaining private space. There must be something to create a natural boundary. Even slugs know not to cross a line of static created by copper tape. This idea always brings to mind Robert's running water cure but having a moat of water churning around the bed all night seems a tad inpractical (if deliciously quirky). A circle of salt seems to work but needs constantly replacing and doesn't stop the rascals peeking in at you.

Please PM me if you prefer. I must get to the bottom of this. I just KNOW the answer is out there. And it's so simple a 5 year old could do it.
