Every time you blink, you get something.

Doesn't matter what it is you get. It's always small enough to fit inside through your door, and isn't harmful to you directly. If you're homeless, the limit is the entire world except for the inside of other people's homes, up to the edge of the atmosphere. If you own multiple homes/you're rich, then the size limit is determined by whichever front door you're closest to.

(As per the obvious negative feedback I was so cruelly given😩, I will take this to r/shittysuperpowers)
