What are hand dreams about?

My freshman year of college I had a dream that my friend who had died in a car accident earlier that year approached me at night, I was in a dark house, and there were people around him moving in studders. He looked at me through a stained yellow window, and I asked him "
what happens when we die?" and he told me, "whatever you believe." After that dream I had another where an aztec man broke through my childhood room glass window and started shedding blue nails from his fingers, until he was just a pile of nails. Like the information my friend gave me was sacred or something.

Cool concept though. If you believe in heaven, you'll go to your brain's idea of heaven. Reincarnation, you'll live the life of some other animal/person. Hell, you'll live in your brain's idea of hell. Nothing, you'll live nothing. Maybe there is something to that, with the chemicals released in your brain when you die, and the few weeks it takes for that electrical activity to completely dissipate in your brain after dying. Maybe when we die, we're at least alloted a brief respite living in whatever colorful fantasy we imagined we might pass on to when we were living, before the electricity shuts off like a light switch and we do too. That dream always stuck with me.

It was a room. Empty. Black, bit with white lines. As if you colored the lineart of the walls white. There were no lights but there was a faint glow, just enough for me to clearly see. There was...something in the corner of the room. Crying, muttering to itself, drawing on the walls with what I thought was a red marker. But as I inched closer, I realized its fingertips were cut off. And it was drawing with its blood. The blood was bright, not like normal blood. It was like, neon red. Very strange.

I don't exactly remember what it was drawing but it was drawing the same symbol over and over again. It was whimpering to itself. My brain automatically went "Help it, it's hurt" So I put a hand on its shoulder. It didn't even jump or get startled. It just stopped everything. It lowered its hand from the wall and slowly turned its head to face me. It had strange features. It was tall, skinny. But it still had like, basic human anatomy. It had a nose, lips, a chest, muscle definition (of whatever muscle it had) It was just a completely black skinny human, but with crazy eyes that were completely white. And they were...scribbly. Like if you took a white pen and angrily scribbled a circle on black paper.

It stared at me for a second, before saying in a raspy, pained voice. " You're like my art in a lot of ways." It moved closer to me. I smiled slightly, " How so?" Its hand curled around my neck, but not choking me, as it leaned into my ear and whispered, " You were created. You have blood. And..." It leaned in with its hands still around my neck, its lips almost brushing against mine, " I can rip you up whenever I wish."

With that last word, it dug its fingers into my neck. Literally. Its fingers went through my neck, piercing the flesh. I choked a little bit. Then like a movie, it cut to a different scene. Back to it drawing on the walls. Then it cut again to it curled into a ball, sobbing, whimpering, muttering. Then I woke up with the horniness of a thousand 13-year-old boys. Which was hella confusing. So like, what the fuck?

Several nights ago I had a dream where a black snake came out of nowhere and bit me on the palm of my palm. I then woke up. Definitely the most bizzare and symbolic dream I've ever had. I've done some research and gotten mixed interpretations. Anyone have any thoughts? Thanks.

Ok, backstories for what I gathered it this dream it was weirdly vivid, this dream takes place in a world where there are humans and neko’s, but humans are racist towards the neko’s, anyways it start with me in a park bent over looking at the flowers, this dream was really vivid, the color of the flowers were blue and yellow they were mixed I think, but I got up and turned around I see a neko in a cloak I think, it was either a cloak or a Japanese outfit, she touched my chest with two fingers and my entire body was encased with ice, then a split second later the neko was gone and the ice shattered like glass, but she was behind me, I was about get up and then my neck started to feel extremely cold, then I think I was knocked out, but when I woke up I got up and headed home, but I saw people giving me weird looks and whispering to each other, i never made it home though, this whole bit is a bit of a blur but I remember I got it a fight, I crossed a little bridge then after that everything was clear again and I was at a friends house, he didn’t know who I was and I was super confused, I told him it was me, and he squinted his eyes and said “Logan?”, I said yeah and he said,”you do notice you have ears and a tail, right?”at first I thought he was joking, until I looked behind me and saw that I had a tail, I looked in a mirror and saw cat ears, I told him I couldn’t go back to my normal job, he agreed with me

I (29F) usually don’t dream much, but last night I had the most vivid dream that I can’t stop thinking about. I was at a small house party, and I walked into a room and a woman was sitting on the couch. We made eye contact, and she immediately challenged me, something like “I bet you can’t...” but I can’t remember what she said. I sat down next to her, I could smell her, see every detail of her summer dress. We were sitting on one of those big leather chesterfields that sticks to your thighs when it’s hot out. We talked for hours and every time someone would look at us we felt obligated to “straighten up” and look platonic even though we were clearly flirting. At one point I think I put my finger in her mouth, just to see what would happen. I remember us exploring each other in very unconventional ways. Eventually we were asked to go outside to do something for the party, take a group photo or something, and I lost her. She was nowhere to be found. She was very similar looking to me, but had a bit of a kinder face and smaller frame.
What does this mean? Why am I so obsessed with her, even when I’m awake, but I can’t identify her?
