The cliff That gave Way beneath My feet

"I was hiking somewhere with a view, not sure why I was up there, just walking along a ridge that felt narrower the longer I went. I stopped to look out at the drop and the ground under my front foot just gave way, soft like wet sand, no warning at all. I grabbed at grass, at a rock, anything, and my fingers closed on nothing. That stomach-flip hit before I'd even started falling properly, and then I was going, wind loud in my ears, the cliff face sliding past too slow, like it was taking its time. I kept trying to yell and nothing came out. I saw someone standing at the top looking down, small and far, and couldn't tell if they were reaching for me or just watching. The ground below kept looking like it was getting closer without actually arriving. Right as the ground finally came rushing up I jerked awake, whole body twitching, heart slamming, hands gripping the sheets like I was still hanging on."
