4 Suited beings intrude through wall

Around 1.30am 4 people as they stood upright entered through the wall of my home 3 -4 meters above ground. They wore silver lightweight hazmat suits with black breathing apparatus. Im Sifu and kicked 2 off me as reaching for the light switch. 2 immediately returned through wall quickly followed by the the2 I kicked.  Whole house was covered only upstairs by a 1-2 foot thick white fog which disappeared quickly as I turned fans on.  I thought all house occupants were deceased from fog. Luckily just unconscious.  Until now this is my first attempt to tell anyone as this is not the first suspicious activity.  Not sure were or who to tell as tracking devices have been found ect.
