As a teenager I would see white orbs or drops falling from the ceiling as I walked through doorways but there would never be anything on the ground. We would also see things move and hear strange noises. I was wondering what those orbs/drops might have been?

Who is "we"?

AND, have you had any vision tests? Wear contacts?

There are many theories as to what orbs are or what they mean. Personally I believe they are just another form that a common spirit will manifest itself as. Does "we" mean others were seeing something as well?

Some - ORBS- are insects flying around it's amazing how they glow at night

And dust.
