Building someone else's character in my dreams

I do not like to admit how much I daydream about what it would be like to have the person that I wanted
I spend time building scenarios that are not realistic to idolize a person who is simply human and who has not made any promises
I create futures with them and what it would be like if it happened
But I got ahead of myself again and I realize that this is not doing me good, inI forgetting who's important and what I want is getting clouded as a result
My next story isn't about who I am talking to and what they are saying because they won't be in my story in a few months
And I can say that with certainty.
Maybe it's my new coping mechanism, because it seems to me as if I have a larger problem with staying at the present. Although it's better than staying in my past, what I'm creating in my head isn't going to happen exactly as is and will most likely be the opposite. There are many unknowns and uncontrollable things about my creations but more when there is a real person in them. If I could remind myself that what I daydream isn't realistic, that the people in them will never do those things in real life I can get back to me. And me needs it right now, I need my head space on me and not creating the same story every night that won't change a thing. I need to build stories that empower me, that showcase my strength and my conviction.
