Alien in a burqa

Date: 11/3/2019

I'm in a small flat which has two floors. I'm upstairs.in a living room? Very modern building. There is an large black sack made from cloth. It feels like a burqa. There is something intelligent inside it. Not human. Cannot make out a form. The sack is lumpy and spread out, like a lumpy blob. It feels malevolent. I hit it with some piece of wood. A cricket bat maybe? It isn't very mobile. It's communicating with me, maybe via telepathy. Something drops out of the sack from an opening where the sack is tied. Where I imagine an arm might be. It is some kind of gelatinous cube. The Alien is transforming under the sack. When it transforms it will be very mobile and threatens to kill me. I hit it again and try to jump over the edge of the stairs as a shortcut. The stairs are a spiral staircase, and has glass bannisters. I get somehow stuck on the glass side panels as the stair case is narrow, and slowly wedgie my way down. All the while I'm nervous this thing will catch up to me.
