What happened to the theory of no LD possible at the beginning of night

I did my tech, which translate me directly into the Lucid dream, what happened to the theory of "no Rem at beginning of the night, you can't have a LD" ?

I got too excited and fall apart in less than 30 seconds. I do it again and achieve second LD, longer but it was very bizarre. I got myself standing in front of a building at night, it looked like a Bank and the next moment a guy a attacked me, we fight, for some reason I had a gun attached on my belt, I shot him. I got over his dead body, in that moment someone knocked me down, I lost consciousness (everything become black) but the dream didn't fall apart.

I woke up on the ground face down, I couldn't move, it's like I have been tied up. Two man were arguing what to do with me, the first wanted to kill me, but the second wanted me as a hostage, I only could see their feets. The first man bring me up and clenched his fist on my throat, he said he will kill me for killing his brother, the sensation of him grabbing my throat was very real and painful. I couldn't move at all and I couldn't scream, I had no control of the scene, it was so bizarre real, I just closed my eyes and wished to wake up, after two seconds I really woke up.

Damn, that SP terror was just too wrong, I slept for the rest of the night.

Normally, having a WILD at the beginning of the night requires first going through a lengthy stage of slow-wave before going into REM sleep. This makes WILDing more difficult at the beginning of the night, but not impossible. However, sometimes at the beginning of the night, we can go through REM sleep before going through slow-wave sleep. When we are able to do this, I think this is most likely due to a phenomenon known as REM rebound. At the beginning of the night, the body is deprived of REM sleep more than slow-wave sleep to the extent that the body prioritizes REM sleep over slow-wave sleep at the beginning of the night.

Your explanation maybe is the best option backed up by science, but there can be another one. As Sageous said in his thread, not Rem state create Dreams but Dreams produce Rem and I fully agree with this. Granted, it can be short and unstable, but still achievable.

I agree. Our mind can influence our biology to a certain extent. I'm open to this possibility of using our mind to get into a dream state on demand. It's worth exploring.
