Dream about my best friends dead mom

My lifelong best friends mom died 7 years ago.

So my dream was We were like at a taco shop and then I walk in and see this woman and she turns and she’s beautiful and it’s like… obviously it’s her mom… and she’s like ITS SO NICE TO SEE YOU YOU LOOK GREAT and hugs me and I’m like omg this is her mom so I turn to her to show her and then I ask her mom “what’s your name??” To make sure it’s her and she doesn’t answer and gets all weird and I’m like “HELLO WHATS YOUR NAME” and then HER EYES TURNED BLACK AND STARTED GUSHING BLACK BLOOD AND SHE GRABBED ME SUPER TIGHT AND SHE WAS LIKE “DONT TELL _____” (she said something that didn’t really make sense )

So I told my friend and she said. Oh when she died she did have blood leaking from her. Which I had no idea before telling her about the dream. So what the fuck?!

And I’ve had dreams with her in it before but weirdly they’ve all been similar, like it’s someone pretending to be her or she’s not supposed to be in my dream.
