How To Stop Intruders? Options

alright so...ive only had this problem once or twice...i guess my dreams arent that interesting but...how to stop eavesdroppers? is there a barrier you can set up while you sleep?

You can block inturders by useing incense (sandalwood) in the area of sleep. Just walk the perimeter of the room you sleep in counterclockwise with it lit and than put it in its resting place. No one should enter or leave after that or it needs done again. If you work with light and meditation you can also bring downa solid white light on you hrad chakra and expand it like a globe or ballon until it encompasses the room. The issue here is it takes a miniscual amount of energy to put up but should not be enough to interupt dream practice.
This can be done to block good or bad entities but ill warn you there is as much to learn from both if you just control the fear.
