Dream No. 20

A lot of rats were smudging around on the floor, yes, house rats, I felt chilly while walking on them...it was a house on top of the building, with open door to the roof...I don't know they are something good or evil, to kill us or to be killed by us...I found lots of birds on the tree while walking on the street this morning, don't know if there is any connection...the end of the world is coming?
