Should I talk to her again?

So this will be a bit long so bear with me. There's this girl we'll call Alice. Alice & I were friends for a good 4 or 5 years in high school before I started developing feelings for her. I told her about these feelings, but we decided that it would be best if we remained friends at that time. Over the past 3 years she's been in 3 or 4 relationships, but I've remained single holding out hope she would feel the same way for me. Her latest relationship started in November of last year & I just couldn't take it anymore. I explained to her how I felt & that while I wanted to see her happy, seeing her happy with someone else was killing me and we couldn't talk anymore. She was sad and upset but she understood.

That was in early November & between then and now we've talked a couple of times but nothing more than a few short social media messages. She broke up with her boyfriend a little over a month ago but I don't think either of us have plans to talk to the other anytime soon.

However, a few months back I had a dream about her where I saw her somewhere and she came up behind me and gave me a hug, and it was the most amazing feeling I had ever felt in my life. That dream made me so happy, but when I woke up I was sad knowing that the dream wasn't real. But last night I had another dream of Alice, and it was us riding around my childhood town on a bike just having fun.

Should I talk to her again? I still have feelings for her and I don't want to risk anything and hurt myself...
