Has anyone else seen orbs?

Okay, so everyone else I ask about this tells me I was either hallucinating, schizophrenic, or on drugs. Which is odd, because none of those 3 apply to me. I decided I'd come to this website to ask about it, as it seems to have a decent amount of intelligent people (and shills too unfortunately).

Okay, so it all started about a year ago. I woke up in the middle of the night, like I always do (I'm a narcoleptic). I didn't know the time, but I believe it was around 3am as it was the second time I woke up that night. I looked in my doorway and saw some sort of white orb about 3-4 feet off of the ground. It was in the middle of the door, and it emitted some sort of very distinct noise. Almost like, electricity? Or energy, and it was a low buzzing noise. I know that sounds weird but I find myself having a hard time describing it.

This pretty much scared the hell out of me, since I didn't understand it, so I just looked away, and tried to fall back asleep. I told some family about this, and most of then told me I was just hallucinating, but my grandma said shes seen the exact same things before too. Little white orbs. Now I found this interesting, that I wasn't alone. Anyways a months went by and nothing more happened.

It was about 8 months(I think) ago that I saw an orb in my doorway in the middle of the night again. This one was slightly larger, and a pure white color. Once again, I just tried to fall back asleep.

So one night about 2 months back I wake up in the middle of the night and I hear that noise. That very distinct, familiar noise. I get up to go to the bathroom, and then went back to bed. I could still hear it, and It sounded like it was coming from my basement.

I went back to bed, and tried to fall back asleep, but I couldn't. Recognizing that noise of the orbs bothered me. Then all of a sudden I remember feeling this warmth, almost like a hot liquid covering my whole body. I also felt a feeling of great peace. It was amazing really. I pretty much felt right asleep. I googled about this feeling and got stuff about the "Holy Spirit". I don't know if that's true or not though. Also, nothing has happened since.

I'm christian, which makes me even more curious about these orbs. Has anyone else seen this orbs? Or heard about them? It's bothering me to have these...experiences, and know nothing about what is happening. I've been told it's the holy spirit, or a guardian angel. I've been told it's simply just energy, and I've been told I'm crazy. What do you guys think?
