1) The sphere decreasing in size could suggest it was being emitted into your room from another location, I'll go a bit in-depth as to why I think this could be.
In terms of Remote viewing, or other phenomenon involving influence, it is possible to effectively make your influence appear at another location.
My though is that the influence punches through from the origin location to the destination, and floods out from a point; influence decays rapidly into a normal background influence pattern.
With the sphere, as described in your account, I would expect a powerful entity to produce that effect if the above is true; it's probably inaccurate, but I'll go for it, as it's an interesting theory to explore.
So, the entity sends its influence to your location, it expands into a sphere, it emits light at you (probably patterned influence, but there is so much it is having a physical effect on the surrounding area, appearing as white light.)
When the entity becomes aware you are aware, it basically retreats, and the influence supplying the sphere reduces until there is nothing; supply could be cut and then the remainder is normalised, or the supply dwindles gradually.
2) The entity could have been in your location to reverse something done by the earlier entity, pure speculation, worth investigating.
After you saw the black sphere, did you have any health issues, or "bad luck"?
3) White, oddly enough, is also the colour of my spiky white ball of non-light which connects me to my body; I looked at it while in an OOBE a long time ago. Wasn't super light-beam bright though, more like the "light" was not glowing and was a physical manifestation in the layer I was in at the time. this is why I'm tending towards the entity influence in 1. Note, I've not tried to visit you remotely, so wasn't me.
Thoughts? (Don't forget, you can always try thinking at the balls [that sounds terrible...])
