To protect your room from negative energies and spirits you can get four quartz crystals (doesn't matter what size) and space them into the four corners of your room( or wherever you sleep) and they will protect you. Just cleanse and recharge every week.

Cool! i will do this when i get some of my crystals
Nice. There's tons of quartz on my property. What do you do to cleanse and recharge the crystals?
I set them into the sun so its power can cleanse them of negative energy and fill it with positive energy
