You can also use your channeling quartz in dream work.
Have a channeller quartz
Cleanse the quartz however you are comfortable with. I like to smudge them but sometimes I'm not able to, so you can hold it in your dominant hand, envision a white light starting from the inside of the quartz and then bursting out from everywhere of the quartz.
Charge the quartz with what you want it to do (this goes with any quartz) Hold the piece in your right hand and send it your intention. If you want to contact a spirit guide, say or think it. If you want to contact an angel, again, say or think it. If you want to contact a specific person on the other side, say or think it. Give it this charge for a minute or two.
Place the quartz under your pillow or next to the bed. You can also put it under the bed.
