Dunno, but your post reminded me of a similar experience I had a few years back

>wake up during the night
>feel a 'presence' in the bedroom
>see a faint white, smoky apparition 
>it's showering about 5-6ft by the end of my bed
>i just look at it for a while, first unsure if it's just my eyes fucking with me so i look away and focus on something else, look back and the same white smoky thing is hovering at the end of my bed 
>it doesn't seem malevolent but I'm pisspoor at reading people so what do I know
>for whatever reason I say something along of that I accept it into my heart
>White Smoky hovers over my body and descends into my chest
>feel a weird sensation inside of me, neither good nor bad
>i get doubt about what the entity actually was
>think i might have invited something unwanted into me a little bit too hastily
>ohwell, fall asleep

Had forgotten about it until I read the OP

lmfao @ >ohwell, fall asleep
Have you felt any different since?

Not as far as I can tell.
I haven't really thought about it that much since it happened. 

It's funny with these sort of experiences, how easily they can be pushed into our subconscious and only emerge when something triggers them (such as your story).

Also interested if anyone else knows anything about these things.
