Strange dream

Dreamt I was going past a shop in the early hours, a hairdresser's.
Anyways a lady and her son (apparently neighbours) were just about to get their hair washed.
The little boy started twitching in the chair and wriggling.

I was with my mum at the time, she turns to me and says "oh god they have nits or tics!"

For some reason reason I notice the lady starts shouting at the hairdresser. I'm pregnant, I think my waters breaking.
I then scramble and start calling an ambulance.
Done time must have passed

They can find us so I walk out to the main road to find them.
We walk back to the shop the shutters are down, so I bang on them and the hairdresser comes out.
Her partner came and she left.

Somehow they are in a car a little up the road. Long story short they tried to scam the hairdresser and me to get out of paying.

The paramedics actually decide to do citizens arrests (?) on them.
But the mother is a master contortionist and manages to break free.
She then starts coming for me relentlessly, attacking me.

I fight back but she's like some terminator and just won't stop.

I finally wake up!

Wth!
