Weird dream lol

Just woke up from a dream where I was in a swimming pool with a creepy old woman with white hair. I don't know her but my mom told me she's my grandma in the dream. She got hurt because I slipped and accidentally dragged her into the pool. Her eyes turned red and I was so worried but I was worried if my mom is gonna kill me doing that. And after that I teleported in my room already showered and drank something but I'm pretty sure it's bleach since its silhouette matches it and I fell down on my bed with a long sigh of relief and I woke up disappointed

Ps: We're gonna go swimming in the next few days
