Are wet dream traces visible ?

Hello everyone,

Last night, I dreamed that I was masturbating and ejaculating (I'm 35 days into nofap). When I woke up, I thought I had ejaculated for real.

However, no trace in the underwear (except a very slight trace of precum). I've never had wet dreams in my life, so I don't know how it results in the underwear.

And is it possible to dream of ejaculating without ejaculating in real life?
