Scared I'll slip up or relapse in the last 2 weeks

Having wet dreams is occurence that happened to a lot of people deep into their streaks

What helped me is needing to have situational awareness, dont let your mind go on a "vacation" and start fantasizing, and be aware for touching yourself where you shouldnt, speaking from own experience i would sometimes touch myself where im not supposed to while i would do random things. Like studying or any sedatery activity...
I would have similar experience sometimes where i would catch myself jerk myself off during sleep - It happens, when i became aware of what i was doing i stopped doing it. Wet dreams happened, i wasnt really conscious in that moment since i was sleeping - cant really blame myself.

Here's my advice. Having some fear is normal, this addiction is a no joke - However its only as big as you give it power to be. Meaning that its you that makes the choices, that has power over yourself and its you that takes upon certain decisions that have specific outcomes that may benefit you or brake you down.
Fantasizing is one of things that can lead to a negative outcome - So, if you want to make your reboot more easier for yourself in the long term, you need to be careful and watch out to catch any fantasizing sexual thoughts and direct them to thinking of anything else and do it every time it comes, might feel whack first couple of times but eventually you'll get better at picking up such thoughts and diverting them to something else.

But you also need to have a balanced view on it and not get too harsh and strict on areas where you're not supposed to.
Meaning, if you want less wet dreams and decrease its chance of happening there are ways of reducing its chance - such as not fantasizing - But you also need to understand that despite the effort wet dreams may still happen. If you manage to catch yourself and prevent orgasm, great, but if it happens that you orgasm while having a wet dream - It happened. None of your progress is lost. You might feel weird next morning or you may not but you must keep going, its important knowing that wet dream wont set you back.

So in a nutshell. Its okay to feel a little scared - But then again there's nothing to be scared of. You're the one in charge and the only one who makes the decision what's it gonna be, some days decisions are easier some days they're harder and that's okay. What matters is that you know you're the one who makes them.
Wet dreams happen and wont harm your reboot, but if you can have them happen less it would be nice - Do a little research on things that can reduce the chances of wet dreams happening.
