A succession of images, thoughts, sounds, or emotions passing through the mind during sleep

I've been randomly having a bunch of dreams again.
It's odd coz as I probably have said before, I don't dream.
I'm beginning to write down what I've dreamt because memories of dreams are very fleeting.

In one I was grocery shopping with her. Happy, holding hands, lovey dovey.
It suddenly fastforwards and I'm walking around by myself and the guy comes up to me.
He's talking constantly, blathering on about something that I never took in.
And then spontaneously, I punched in. In mid-talk.
He went flying. Far.
Landed in this big random pile of wood (?).
She went to his rescue, berated me for what I had done and left me to carry on with 'our' shopping.

The next dream really felt like... another day.
I went to her work, looking to buy some clothes.
She saw me, ran to me, hugged me, kissed me and we talked for what felt like forever.
Talked about everything from clothes brands to animal locations (?).
It ended... uneventfully.

This next dream is odd. Its recurring. I don't know about everyone else but I tend to have a few recurring dreams in my life which always haunt me for whatever reason.
I'm all dressed up sitting on a pew in an impeccable church with bright sunlight shining through each of the stained glass windows.
A friend is sitting next to me, but there's hundreds of other faceless people sitting around me.
She walks in, the bride, and he walks in, the groom.
They walk up the aisle, waiting for the priest to recite his timeless speil.

"If anybody has any objections speak now or forever hold your peace"

I sharply stand up in the deafeningly quiet church, gripping the pew in front.
Everybody's blank faces turn to me. My mate chastises me angrily, "What the hell are you doing?!"

I look to her, half wanting to say something but half knowing I would probably not survive the trip to the door if I do say it.
I look deep into her eyes, the physical distance between us seemingly disappearing.

I just walk out. What could I have done?
That definitely is an odd dream. Recurring at that as well.

I do wonder if it means anything?
