Really long, strange dream

So I had a super strange dream last night and I have noooo idea what it means. Can someone please help me decipher them?

It starts off while I'm away at school. I meet this kid, who seems to be a lot older than I am. He isn't a kid that I have ever met in real life, but in my dream, I really seemed to know him. He was super tall and had bleach blonde hair and blue eyes. He was a bio major like me, but instead of a pre-med track, he was on a botany track, and so we walked into a greenhouse. This greenhouse, though, looked absolutely nothing like the one at my school. We sat down on this wooden swing and talked. He was mumbling a whole lot, so I really couldn't understand him, but I pretended I did and just nodded and stuff like that. After we had been sitting down and talking for a while, the one of the adviser's for my school's Habitat for Humanity came up to me and asked me to follow him outside. Now, in real life, I have a huge crush on him, but he is like 10 years older than me, so I know it's not going to happen. When we got outside, he handed me a lacrosse stick (I have never played lacrosse in my entire life) and asked me to help him practice something called a smuf. Meanwhile, all around us there are people doing super athletic stuff, like running and jumping over stacks of tires (I don't know why tires haha). So I tried to help him, but I was just awful. Finally, we sat back down and I started showing him pictures of my family on my iPad (I don't actually have an iPad in real life though). There's a whole bunch of pictures of me and my sisters, and a lot of horses and people horseback riding, which is something I absolutely love. We came across a picture (one that doesn't actually exist to my knowledge) of me, my two sisters, my best friend, and a girl we all used to be friends with but who changed when we got to high school, from about 10 years ago. You can kind of see like my mom's arm or back or something in the picture, but that's about it. The adviser points to the picture and asks, "Who do you think is going to get married first?" Without even hesitating, I tell him "I am, because I'm the oldest." He gives me a strange look and I get super embarrassed for some reason, so then I tell him, "Well, maybe my sister Briana." I then find myself back at the bench with the first guy, but this time, there are a bunch of pillows, so we snuggle together for a while, but I'm still thinking of my adviser. Now, I used to work at a library as a shelver, but I had to quit when I went away to college. In my dream though, I look at the clock and see that it is 5:00, and I have to be at work at 5:30, so I just freak out. Somehow, I end up in my room, even though in real life, I live 4 hours away from home, and start getting dressed. Time goes by quickly so it takes me 20 minutes to get dressed, even though I usually only take about 5 minutes, so I'm totally panicking. I don't have time to eat dinner, so I shove candy in my pocket and grab a plum from the kitchen. My family drives me to the library and I go inside. It's still the library, but I could see that there are small differences. Instead of going behind the desk to clock in, I go to the break room, which is about ten times larger than it really is. Still, it's a squeeze because almost all the workers are there, including a whole bunch of people who either went to high school with me or who worked at my high school, most of whom I rarely talked to. In reality, there are only maybe 7 people working a shift at a time. After a few minutes, everyone stands up and we hold hands and stand in a circle. We start walking around in a circle and singing this song. After we're done, we all leave, and I realize that most of the people in that room were shelvers as well, I'd say about 15 people. Everyone scrambles to try and find things to shelve, because if they see you not shelving, they were going to fire you because they thought they might of hired too many people. I grab a few VHS tapes to shelve them when my phone goes off. When I grab it from my pocket, I see it's my old Samsung Glyde, the phone I had before the one I have now, a Kin 2. When I answer the phone I hear someone say, "Hi, this is Dawn, -----'s mother." She repeats it twice, but I still can't hear whose mother she is. She then says, "We found your phone in Nicaragua. It was in the hands of oversea terrorists." She then goes on to tell me that my family and I are going to be put in a protective custody because the government was afraid for our safety.

And then I woke up haha. It was so strange and it had soooo many strange details. Help?

Ok, so just to add, the girl in my dream that we're really not friends with anymore, stopped by the store I was working at today. I haven't seen this girl in like a year. What?!
