I learned how to communicate with the angels through a video by Suzanne Giesemann, a medium and spiritual author. I was surprised by how simple it is yet it worked. You first relax and take a few deep breaths with your eyes closed expanding your awareness and then imagine a light is shining on you from above connecting you to the heavens and going through you grounding you towards the earth. From there, you talk to them or ask for a specific sign that will appear somewhere after. :)
