Relapse?

Morning, evening, afternoon to all.

I had this wet dream of me watching porn but I was actually there at the shoot watching the whole thing, I felt the tense and all that. It basically felt like I was the one having sex with the girl and slowly I felt my penis getting rubbed slowly, then quickly and this huge orgasm coming, I soon realised its a dream so I was like.. fuck it lets see how this ends.

So I started cummin and when I was half awake I felt my body rubbing rubbing my shit on the bed and all this semen blasting out.

Like wtf? I dont understand how this happened after so much progress. Though I convinced myself to let it go like it never happened and continue with my counter and progress but I cant help but realise I relapsed. What now? Is it really a relapse?
