I so much prefer the expression day dream to fantasize. However, the only time I broached the subject with a T he called day dreams fantasy. I spend my only happy hours in my day dreams, but now I'm so depressed that I have lost the ability to day dream, let alone be happy there.

I started day dreaming because I have trouble making friends, in the past these other lives have been so real for me that I spoke out loud during conversations while day dreaming.

If day dreaming puts you at risk of harm or neglect then it may be a problem, but if it keeps you safe and happy then OK, but don't get your other worlds and this one mixed up and don't disconnect from real life entirely.
