The memory replays in my head
Like a never ending roll of tape I think you could've used a better simile here. Honestly, it doesn't seem to fit - after all, have you ever seen a never ending roll of tape? I guess it could be possible, but it doesn't fit. Suggestion: change it.
So vivid that all sense of reality is lost Liked this line.
Held deep within the corners of my mind
A simple moment
An inconsequential slice My question is, how's it inconsequential if it means so much to the main character? Hmm... I suppose it's inconsequential to others...
Your arms draped around me
Your tight grip shielded me from the world
I lost all consciousness
For a few seconds
It was only me and you
Within a lifetime one has
Countless amounts of moments like these. This does good as it is but I think you need it more transition-ish, y'know? Yeah.
It’s the moments you least expect
That will hold onto you forever

This was pretty well written. The emotion was sort of there but sort of not, though. I liked quite a few of the lines anyway. Pretty much, good job with this. :p

Like a never ending roll of tape(comma) there's no need to capitalize the beginning of each sentence. Unless you feel it's important to your style, treat sentences like you would with prose (though you do have more freedom with poetry)
So vivid that all sense of reality is lost (period)
Held deep within the corners of my mind (comma)
A simple moment(dash)
An inconsequential slice (period)
Your arms draped around me (comma)
Your tight grip shielded me from the world You said 'draped' but now you're stating they had a 'tight grip'. This is contradictory.
I lost all consciousness This is why punctuation is very important. I don't know if you 'lost consciousness for s few seconds' or 'for a few seconds it was only me and you'
For a few seconds
It was only me and you this should be 'you and me'
Within a lifetime one has countless amounts of moments (comma)
It’s the moments you least expect
That will hold onto you forever (period)

I really liked your imagery, especially the last line. Kudos on that aspect, you're very good at telling a story.
