Swinging during a thunderstorm

((Warning for creeps))

I forgot a great deal of this dream simply because one image I had in the dream overpowered everything else and I couldn't think of anything else.
I remember being overwhelmed by sorting clothing.
Something about a museum greenhouse I wasn't supposed to be in but went in anyway.
There was a time limit. I had to be somewhere soon.

Anyway, the most important images I remember were that I couldn't sleep and so I went outside during a thunder and rain storm to swing on a swing-set. I tried to get as high as I could but the chain snapped and I fell backwards, no harm done other than swinging in the rain in the dark.

At some point I went inside which happened to be some sort of shop and on my way in I saw this very creepy old woman with I think it was a tall man and a shopping cart. I tried to warn my mom about them but they knocked on the door and tried to come through even though we had put up our closed sign. They pushed open the door with the cart, the little old woman exclaiming, "Ooopsies! Elbows..." as she tried to push her way inside, her voice so feeble and adorable but everything else about her screamed 'CREEPY' so I grabbed the cart and stopped her.

Her face morphed into a demonic one. She hissed and shrieked at me and growled. Her eyes went black, her jaw stretched beyond normal human capacity and the tall man disappeared from behind her and reappeared like several yards behind her in the blink of an eye. He was at least 7ft tall. I tried to tell her she wasn't "welcome here" but I couldn't find my voice. No matter how hard I tried I couldn't tell her to go away. It was like any noise I made came out as a squeak.

I automatically began to tell myself I must be dreaming and I began asking help from Gabriel (hey, I was scared, she was fucking creepy). I began pulling on my pinky (one of my dream tells). She eventually backed off enough I was able to shove the cart back out of the door (she never crossed the threshold) and I bolted the doors.

I knew there were other windows in the house/shop I was in and all at once I could hear something banging on the glass on every single window at once and howling. Then it all suddenly stopped. The rain stopped. Noise stopped.
I looked out the window and she was gone and so was the tall man.
