What are garden dreams about?

I had this nightmare when I was about 6 years old and its stayed with me till this day.

In my dream I was in a garden and i had a baby but the baby had a very large head. The garden was overgrown and had steps going up to an old table and chairs. My baby was walking up the steps and all of a sudden fell and hit his head, his head broke like it was made out of glass. It shattered and when he stood up he was stumbling and made a horrible inhuman cry. I woke up and was in hysterics. I was absolutely terrified to go back to sleep.

(Apologies in advance: I'm on mobile. I just woke up in a panic and had to write this out!)

I dreamt that a close childhood friend and/or my sister killed a man and I helped them bury him in a garden in my yard. (Mind you, this also took place in the house I grew up in, not where I currently live.)

The remainder of the dream was guilt ridden and panicky as I attempted to come up with a way to stay out of prison. I was jolted awake after walking to my front door and seeing a note from an officer asking for a call "to chat".

I'm struggling to find meaning in this. Maybe I'm having massive anxiety? Maybe I'm repressing guilt or anger or shame? Maybe I murdered someone?!?! (Just kidding on that last one...)

So, I'll describe the dream with the brief details and little narrative that I remember. No matter how strange

So I remember being in some kind of large house which was an orphanage? Or something of the sort, for some reason that old cartoon, fosters home for imaginary friends comes to mind.
I remember a lot of random children being there, I didn't recognise any of them.
I was an authority in this house, as I remember helping some of the kids and they were asking me things etc etc. (only mundane everyday things).
Anyways, a bit 'later' two little girls were starting to complain about a boy, he was a bit older than the both of them. He was abusing them and being really nasty to them.
When I went to confront him I remember catching him trying to bite the arm of the little girl(I'm not sure if he actually managed to take a chunk or not). His mouth was opened extremely wide like a snakes. At which point the dream quickly devolved into a nightmare, I chased off this little boy, but he was suddenly some kind of monster(demon?).

I chased it out of the house that I don't recall the layout of into the back garden which I immediately recognised as my fathers garden. At which point my brother appeared in the upstairs window shouting ''You have to get the 'Gremlin' out!''.

As I was approaching this monster, the little boys face and form were in a constant state of shift. Had black eyes and a cavernous black mouth. Eventually turning into some sort of dog. As I got closer the monster dog was trying to escape, I remember using some sort of superhuman strength to knock something over to block it's path at which point it lunged at me. That's when I woke up.

I was super creeped out for a while after waking up but, I'm not sure what to make of it!
The details I remember most are the black eyes and mouth/weird face on the monster.

Any opinions are welcome!

it begins like that: i was playing games at midnight until someone called me at the phone, it was a girl who asked for help and wanted to meet me at my garden, without thinking, i jumped off the window and landed on the grass, she was there, kinda looked like an astronaut, she had my same age... but she had no body, there wasnt a face behind the helmet, She was just the suit itself... i feel like she looked cute trough... she talked me about a big journey she had to make the next day to another world, she told me that the route was dark and she was afraid of "creatures", she wanted to bring me with her, "to have someone to hug when im scared" she said, i accepted, she gave me her number, and we talked all the night at the phone, she was very shy and didnt want to sleep with me because she was afraid of my drunk parents, i told her i could give her everything i have to make her happy, i could hug her whenever she wanted, i could sacrifice myself for her, and other sweet things i dont remember, and then she said, " [my name] , im in love with you", then i said i wanted to meet and talk at my garden, she told me that she was running thoward my house, i sit on a bench outside and waited for hours, then i saw her, she was running on the street, i screamed to come there and then something horrible happended, she had been run over by a car, and then, i woke up. I felt lonely and guilty for the rest of the day... life sucks.

So I've been attracted to my boyfriends best friend for a while now and it seems it goes both ways. I've talked to my bf about sharing me a while ago already and he was completely against it and whenever I brought it up again he got mad at me so no chance that this will ever actually happen.

Anyway tonight I dreamt of my boyfriend inviting him over and I was wearing nothing but some cute underwear and they both started groping me while we were in the garden. And then his friend opened his pants and took out his cock and first fucked my pussy raw, then my ass until he came. I should probably say that my boyfriends best friend has only had sex twice in his life and I'd love to show him how good it can be because I've heard that it wasn't so great for him the last two times.

So now I'm thinking about just sending him a message confessing to him that I'd like him to fuck me... but for him to please not tell my boyfriend. But I'm not sure if he would do that
