Dream are symbolic expressions of your feelings about your waking life at the time of the dream. The meanings of the symbols are informed by their context. Like words in English (or in any language), their meaning is determined by their context. When it comes to dreams, that context is informed not only by what is going on in the dream, but by the waking life background of the dreamer... because that's what generated the dream. Without knowing what was going on in your waking life at the time of the dream, it's hard to be conclusive about its meaning. However, there are some important clues and symbols in the dream that should help you figure out not only its meaning, but why you had it.
The dream is set in a crowded setting with people you know. Who those people are (are they students, friends, teammates, etc) is a big clue as to which are of your life is on your mind. Given that you are talking about going to college, I assume that they are classmates or fellow students... and this dream may be about the college entrance or matriculation process (in your mind).
But, who is the stranger. Strangers in dreams are frequently people we know, but we conceal their identity for reasons that could range from the fact that you are protecting yourself from that person's identity to you really don't know who it is. What happens next should help you identify who it is. He (so we know it's a male and you say he is your age) starts to bite you and suck on your neck softly. That is what vampires do. To understand it's meaning, here's a link to its meaning on this website:

The definition offers several clues, one of which should resonate with you and help you identify who it is.
1. When a vampire bites you, you become "one of them." Also may be associated with people who "drain your energy" and "suck the life blood" out of you.
2. Vampires are common in the dreams of teen girls, who are concerned with questions of losing their virginity. The masculine vampire will "draw blood" and make the dreamer "one of them" (a non-virgin!) Is someone trying to initiate a new behavior with you?
Another big clue is how you felt IN the dream. He felt scared and he wouldn't let you go. Feelings in dreams are never disguised, so how you felt IN the dream is how you feel about this person in your waking life. Bottom line, you feel scared that this guy will "bite" you and not let go. Sounds as if it's an uncomfortable relationship issue. Your dream is telling you that you don't feel comfortable with what this guy and/or wants from you. It's telling you to beware and keep your distance before he puts his teeth into you.
Hope that helps you figure out his identity!
Stay safe!
