Ankle licking

I was on this stainless steel bridge that was spaced like a toy rope ladder you’d find at a park, where the rungs are very spaced. I was talking to JM from elementary, when suddenly he says “[name] it’s okay I got you just keep walking forward.” I look down and idk how I’m supposed to cross the rungs w/o gripping w my hands. JM is behind me literally enveloping the back of my body. I feel this fear and suddenly I feel something in my ankles repeatedly touching them. I look down and it’s a creepy old man licking my ankles. No matter how fast why try to run he keeps licking them, crawling behind us
