It's a sign of recovery, even if it doesn't feel good in the first hours after realizing what happened.
I (20M) had 2 sexual dreams ~2 weeks ago, with 1 normal night in between. I felt very disappointed because it happened during light sleep and I felt like I could have prevented it with enough willpower. But it was just a dream and I simply wasn't able to control it.
Writing this, I remember that when I had the second dream, I think I actually was able to wake myself up to get out of the dream, but physically it was too late.
The only advice I can give you is: * quit social media (suspending or just logging out of account should be fine for still keeping contacts) Since it's invention, these platforms where designed to keep you hooked - to make you addicted to them, just as porn made us addicted. Always seeing a new post, always having the possibility to find the next best post.
Since over a year now I haven't really used social media...except one twitter account (for reading news; deleted aswell) and one (now two) reddit accounts for both NoFap subreddits.
When I was using social media, it was impossible for me to stop doing this sin. Now that I don't really consume content on social media (except some youtube), I feel like temptations decreased significantly.
Sorry for the long post
God bless you!
