My sweet mom, who's no more, experienced something once (I'm curious about it now) and I don't know if it is AP or Lucid dreaming.

It's gonna be a long story. So, my mom had 4th stage liver cancer since 2024. She used to tell me that sometimes she can take control over her dreams. And we used to discuss about these topics. So, one day, most prolly it was 5th oct, she was sleeping in a different room and for past few months her health was deteriorating sm. I was in my room, sleeping and my dad and sis were in another one. It was 1 a.m. My sis went to washroom and suddenly heard some noises from my mom's room and she went there and found her being sleep paralyzed. She woke her up and then what she told is---- My mom was asleep by that time and suddenly she felt the urge to pee. When she lifted her hand up she saw it was weightless and her real hand was still in the bed. She tried to woke her body up but couldn't. She got frightened and immediately went to my dad's room and woke him up saying "please come with me, see, my body is laying in the bed. I'm dead, na! Because I'm not in my body, can you see me?" Then she saw my sister as a little baby but she's 18 now. She hold her in between her arms and came to my room and asked me the same question if I could see her. She said that I didn't care and went back to sleep but I said smth although she didn't remember after waking up. Then she again went to my dad's and suddenly saw a giant black bodied structure, holding maybe a scythe in his hand, was ready to take my mom. She was pulling her and my mumma was crying holding my father that she didn't wanna go, she wanted to stay with us. For how long this went on, wasn't known to her. It ended when my sis woke her up as I said previously. But the thing was after that she was improving gradually and we were happy but all of a sudden again her health deteriorated and she passed away on 17th Dec '25. I've been thinking too much about this since the past few months, and posted finally. I've some idea about it but idk what actually it was. I just wanna know if that was a signal that she's not gonna be with us anymore and if this is then why her health did keep getting better. Any kind of help would be appreciated and if you're still here reading this, Thank You.
