What are tunnel dreams about?

I was at my hometown house from childhood. I saw that there was a nuclear disaster far off and we lived in a vally.

The hillside was liquifying so I took my friends uphill. There was some kind of tunnel system through a building set into the hill.

I navigate through this place with doors and hallways but I lose my shoes at some point. We end up on the other side and there is snow on the ground.

We are at high elevation, but I'm more aware that I'm without shoes. We get into a car and see all of the panic traffic caused by the disaster.

At this point I somehow rewind time to before the disaster. I'm back in the vally and I get shoes and a nice backpack from my brother. I think to myself "man these are nice boots, it's nice that they're not valuable yet and I can just pick them up"

I try to explain what's about to happen to my brother but he won't listen.

I only remember one part I don’t know how I got there or were I was but it it had a room a hallway. It was all red a blood red.

“I kept hearing Azazel is coming” and “that he is here.”

I tried getting away running from him. I tried going through this tunnel crawling through it but I was scared he was going to meet me at the other end and that he would crawl behind me. I got out of the tunnel and ran down the hallway and was met with a room with a bed.

There was two men in that room all scared unknowing. Then Azazel came out of an elevator he said he needed help he had two stones a necromancer stone and another I cannot remember the name of. He carved a symbol into one of the mans back and took him.
Azazel never looked at me acknowledged me but I just knew he knew I was there.

What he looked liked: red skin beard horns

Please if anyone knows what this means please tell me I’m so scared jumpy and do not want to go to sleep I suffer from sleep paralysis so this makes it even worse

I had a dream where it seemed to be everybody’s last day on earth. We were all free to live out the rest of our day doing what we all wanted to do before dying. The things I did seemed to be fighting someone I had disliked, as well as meeting my favorite music artist. As the day reached closer to the end figures dressed in all black stood on the sidewalk seeming to stretch on endlessly. Standing like soldiers. A deep fog rolled in, and soon people were getting killed in seemingly random fashion, but as soon as I was killed I understood. The deaths were ones that represented whatever sins the person committed. An ironic death for all. After I died, and others too, the souls remained and got to see the ‘dark parade’ thats what I am calling it anyways. In it wooden carts with dead bodies stroll down the road and into a tunnel where me and other souls were. Many souls began crying as their family members pass by on the wooden carts, the souls disappearing when their own bodies pass through the tunnel completely. After all bodies pass including my own, which seemed to reach out to me as it passed, the black figures began to do some kind of ‘marching dance in place’, while they did some strange maneuvers that I really cant explain. After they finished, every single figure walks into the road and simotsiniousloy die at once. This is where I woke up.

I will being by saying I am suffering from depression and I have many unanswered questions . I’ve been dealing with grief and loss and I’m overall not happy . I’ve contemplated things I’m not proud of . Many times I spoke to God , to heaven , thinking no one was hearing me .

So , I dreamt about seeing people going inside a golden tunnel I knew they were the souls of the departed . This angel grabbed me , I couldn’t see the angel well as he or she was walking behind me but I caught a glimpse of them : tall , golden locks , blue eyes and a blue and reddish / maroon dress , big wings ecc ….the angel spoke to me telepathically . We were walking in this golden place maybe a palace , with Golden Arches and columns … there were many souls there … the angel had a lion right beside them who was following them … it was a docile lion : his fur was shining like stars and you could pet him which I did . The angel spoke to me . He addressed me . He said “you have your life ahead of you . Live it well . I know about your questions . I know many people don’t believe it’s true but there is life after death …” - I’ve been dealing with the loss of a family member -

As we were walking I could see a lot of images on the walls , paintings , the light was beautiful I felt like there was a lot of acceptance . And love . The angel said “I know you have been sad” after that , he brought me to see a sheep . She was an old sheep I know it was the soul of a departed sheep although I could see her as if she was actually made out of flesh and bones . The angel took me to a place that’s hard to describe : it was like the other side of the tunnel it was like a gate and souls were passing right through it to reincarnate , which is what the angel told me. They would descend on transparent stairs . The angel took another sheep and he helped her cross through the gate , as soon as he did that , the sheep became a baby , a lamb . “She’s ready to come back “ said the angel . “Once outside of these gates the souls don’t belong to us anymore , which I know can be scary . The fear of the unknown . But you have to know , as soon as they cross to come back the lord is already there . The lord is already there “ the angel told me to help the sheep cross to become a lamb and come back on earth . As I was doing this , the angel repeated “the Lord is already there “
I woke up crying . It was an amazing experience . My questions were answered . Although I am a believer , I am not someone who is interested in Christian symbols .
Why were there lions and lambs ? I didn’t watch any movie regarding this .

Was that a glimpse of heaven ? My questions were answered .

Hi guys...

Today I had a very strange dream...

I was sent in a different world where there was a God or something like that ...

I'll skip the other details and get to the ending...

So in the end I was in something that looked like new York with plenty of tall buildings and very colorful but it was not new York... anyway then everyone began to pray or something and 1 Giant appeared out of nowhere and he was giant as the empire states and he was vivid bright blue and was emanating a light and when I came close to him to send me back in the future where I was from he first pushed me and called me something like Samael...

And then when I came a second time I began to pray and then something like a round mini sun began to form in my hand and was growing gradually,

And then a tunnel of light began to open before me and then the Blue vivid bright deity approved of me and allowed me to go , and I went into the tunnel...

And I was sent in the future I suppose?

Any idea what it means...

Also why call me Samael as the Angel of Death??
