i just had a strange dream last night

I dreamed of someone ripping my hand with a scissors in front of a cupboard, and there's a lot lot blood on my blue cardigan. It's not painful, but the blood spilled everywhere like those on horror movies. I scream for my mother, and suddenly she came and washed my stained clothes.

What does this mean?

And also, sorry for being so sarcastic in my last post. I just not in a good mood.
