I am 30 yrs old female. Checking phone!

Since many years, I behave crazy when I see or I am around a guy or especially in talk with any guy. When I am am talking to a guy over chat, I go into a different dreaming zone and I instantly start imaging scenarios with the guy no matter who he really is. I leave reality and mostly go into that dreamy high zone. I lose my mind. I am willing to talk to any guy and I am really tired of all the repetitive thought process, losing reality, losing sense and time. I have no clue why this happens to me. Scenarios mostly includes hugging the person, getting cosy, the person appreciating me or I am kind of proving my point in front of a third person and the guy being there. The scenarios also have romantic eye contact,  guy appreciating my beauty.The plot usually is any Bollywood scene. I know this might seem funny but m highly stressed and want to understand the psychology behind this issue of mine. I want to not lose reality and go crazy, pls help if I chat with guy I keep checking phone
