I feel like this song is about leaving someone or something you love. They're like fireflies lighting up a dark night. "Stay awake when I'm asleep" could represent the feeling when you are too tired to stay awake, but you don't want to go to sleep, since you may never see the person again. It could also mean you've stayed up late enough that you're no longer tired. The line "I get a thousand hugs from a thousand lightning bugs" could represent hugging each other. "As they try to teach me how to dance" could represent them trying to teach you something special. "Please take me away from here" could represent wanting to leave the moment of uncertainty and sadness you're currently in. "I'm weird because I hate goodbyes" could be because everyone else can stay in contact and you can't, or you feel weird since you're the only one crying. The misty eyes line could also reference to that. "I saved a few and keep them in a jar" could represent a phone number or address to keep in contact, or even just a picture to remind you of them. "Because my dreams are bursting at the seams" could mean wishing and dreaming to get back together someday. I hope this helps you!
