In the last days there will be a major uptick in the interactions between demons and mankind.  This has been seen extensively in the ET phenomenon.  There will also be a major explosion in the amount of demonic activity worldwide.  This is already evident all over the world as the demonic activity is very out in the open now seemingly without any shame or reservation.  It's a very "in your face" experience now.  The only way this can get worse is doing the Tribulation when it will take yet another big step upwards in activity to the point where Hell will quite literally be released upon the Earth.
