Coincidence or Demonic entity?

Not demonic, demonic is usually affiliated with demons, evil spirits. This didn't do anything evil. It didn't hurt you or cause any harm. It may have been spiritual, however spirits don't need electricity to function. There is enuff energy in the atmosphere, like the sun and other natural sources. Yep, your reading to much into this. What would be the purpose of doing all that to you, and not show you what it wants or wanted. When u were sleep, you dreampt that you woke up. You were still sleep and under sedation from the Nyquil. Contrary to popular belief, spirits don't hide out in closets or basements and they don't need anything in "our world" to survive or communicate.
