I think one of the neighbors brought spirits to our building

I do understand what you re talking about.
Those Shadow-Creatures and "Creatures" is a good name, are scary to even natural Spirits that want to be around you.

I've mentioned before that I have two Aunts that very frequently visit me and they have mentioned these Shadow Creatures/People. 
I am not a Sensitive or have real paranormal abilities, but I guess if you have friendly spirits or long past relatives that like to visit they can make themselves seen and heard, mine do.

My Aunts have warned me before about Things Attached to a Patient I've treated and I had a patient that was Dying and there was No Way to help this person, they told me this person having the Life Actually Drained from his/her body by Creatures/Entities this person had brought upon themselves.

Yes Joy, Love, Laughter, Light and Happiness keeps us all Healthy in Many Ways.

That is good to know, but also very sad. The creatures haven't hindered my relative from visiting so it reinforces my impression that they aren't here for us. I feel bad for whomever they may be here for though.
