Is this salad still good after leaving it out for....?

I made a small bowl of salad before bed, brought it to my room but fell asleep before I could eat it. I only put on it olive oil and pure apple cider vinegar, tiny bit of water, plus salt and pepper. So it was in my room, covered with plastic wrap, and I put it in the fridge when I woke up. It only looked a little soggy from the vinegar and moisture of course. It was pretty cold last night, gotten down to the high 30s/low 40s. The salad is mixed leafy greens, dark ones, plus the very dark red-purple pieces, NOT Iceberg type. So is still fine to eat or what?
