Since I moved in this apartment, like mad of occasion I've see orb. It looks like a white round fluffy or a white round smoke that's floating within the air,corner of the room or on the ceiling. It appears usually when I purely wake up, the moment I open my eyes (in the middle of the night or even contained by the daytime), I will see this. It made feel alarming, but I don't know what this is.
Answers:    I agree with 'the shop'. This could be mystic. But, since you say it is white, it would be a honest presence. I have hear that sometimes it is a Godly protection or a loved one that is watching over us. My daughter experienced something approaching this soon after my mother in ruling passed away.
I would video it for at least 5 minutes and embezzle lots of pictures. I hope these links help. Sounds similar to your story.
I almost don't want to be the one to tell you but this is usually an indication of a mystic presence. It's important to save in mind though that not adjectives presences are necessarily threats. Try taking a picture of it or better yet find it on video, as this may lead you closer to what you necessitate to know.
P.S. Make sure to rule out any natural cause for this "Orb" that may have cause it to appear such as an early sunlight or something approaching this, is it really out of nowhere, and does it float around with no fine direction? These are the questions you want to research first.
