<human>: Give me the gist of the text in a nutshell

Background:   Me and this girl, we will call her Sam, met freshman year of high school and became friends.  Fast forward to senior year and we got really close, we would buy each other gifts, walk each other to class, and were flirty with each other.  People saw us as a couple and we went on a couple casual dates but nothing was ever official.  I was always afraid of starting something because I knew I was going away for college.  I was this fear that held us back from being anything more.  Sam and my conversations slowly died down to a halt when I left for school and I haven't reached out to her since freshman year of college besides the occasional facebook or instagram like.

Currently we are both juniors in college. This may sound strange, but out of nowhere two or three weeks ago Sam started to appear in my dreams again.  This made me realize how much I do miss her and how much I regret letting what we had of a relationship die down a few years ago.  I coincidentally learned, while looking at past pictures of us on facebook, Sam had broken up with a boyfriend a little over a month ago and is currently single.

Now I'm not sure what to do.  I would love so much to resurrect what we had senior year of high school, even if it meant long distance.   I really don't have a clue what her reaction would be. I know that is best case scenario and it may just be more awkward than anything.  Should I just send a text out of the blue trying to catch up and treat it like a completely new friendship? And if we do start talking again do I try to move forward with the relationship?  Any input would be greatly appreciated!

Thank you for your help!
<bot>: I want to reconnect with a girl friend I had a semi-relationship with in high school after 2 years with little contact, how should I go about this if at all?
