I have not experienced orbs, yet. Within the last month or two I have started to see images on my ceiling when I come out of the hypnogogic state twixt sleep and awake. Sometimes they look like a portal, sometimes like crab, insect or similar, sometimes light flashes. I have intutited that it has to do with how I am vibrating in that state and I look forward to being able to hone this--to "collaborate and experiment to find a frequency."
