Almost shifted last night?

So last night I didn't really try, or only for a short period of time, but I did have a Lucid Dream. I still need practice with Lucid Dreams, because I tried to do the Lucid Dream method, yet every single door I found just lead to a regular ass room. Which was quite frustrating. But, I woke up because of something 2 hours prior to my alarm going off, and I just attempted to gaslight myself, in that delirious state of mind that one is when just waking up. And for some reason, it felt like I was in two realities at the same time for just a few seconds. I don't remember even how it happened, because I quickly fell asleep again, but it was as if I was in my DR (third perspective I believe) and fell asleep at work, and one of my friends woke me up by talking with me. Again, I have very little memory of it, and it was third perspective, like, really delirious, as if I ALSO just woken up in my DR (which would make sense given that I also just woke up there) and I wish it had been longer so I could've been certain, but whatever the case, I fell asleep way too quickly and woke up again in my CR. Maybe it wasn't a shift at all and I was just imagining it? I'm not 100% sure though. All I remember was Tavern, wooden table (which I was sleeping on) and that DR friend, not even how I was looking like. I also remember that for a few seconds before falling asleep again I was very excited.
I don't even know if it was 1st or 3rd perspective because of everything... Does anyone know whether that might've been real? (ik this might sound stupid as I was the one to experience it, but that was the closest thing to a shift I've felt in all of my 3-4 years...)
