Thread: First lucid dream? [pls help]

So I went to bed at 11pm. I kept repeating two mantras until I fell asleep: 1) I will wake up after every dream. 2) Tonight, I will realise I'm dreaming. Ok so it all happened at about 1.30am. So in my dream I was standing in front of some entity who was sitting on a chair in a grocery store. We were just watching eachother, no one moved. I suddenly thought to myself: This must be a dream!? Right after that I could see my body sleeping on my back and It felt like I had two bodies, 1 in my dream and 1 laying on the bed. Then immediately after I woke up. I could still see the entity in my room. It was like a vision. I kept observing it and after 5-10 seconds it disappeared. After that I sat up and did some reality checks cause I thought it was a false awakening. But I was officially awake. My heart was beating quite fast and I was so happy and excited. I think I was lucid for a second and then I ended up in sleep paralysis cause I could still see the entity while I was laying in my bed. I never tried to move though, so I'm not completely sure if I was fully paralyzed. So I have a few questions:

1) Was this my first lucid dream?
2) Did my dream end because I got too excited?
3) Or did my dream end because I 'woke up' at the end of my dream cause of my mantra? Because apperently REM is quite short in the beginning of the night. And everything happened at 1.30am.
4) Do you think I ended up having sleep paralysis after the dream?

I've never experienced something like that in my whole life. I'm still amazed tbh ;o. I fell asleep while I was laying on my left side, so I think I must have rolled over onto my back while I was asleep xD.

Sorry for my bad English btw!!
