What stops people from lucid dreaming?

[Seltiez]

I have seen so many threads and post that some people cant seem to have lucid dream no matter what they try. I have been thinking if the someone does the work that it claims to do or could it be some mental block? I dont know. Is it their belief or just lack of even 1 lucid dreaming experience? My first lucid dream that i remember fully and amazed me came when i had different views on reality. "I just thought i only experience reality trough senses maybe there more?" Months after that pondering that i realized once i was dreaming tried to touch the wall and observed how it felt and i was amazed how real it felt then i woke up deilded back which blew my mind. Since experiencing falling asleep with awareness. I googled it and found this page (Which im thankfull i found nobody believed it was possible to follow yourself falling asleep). So is it just realizing that reality could be more and being open to questiong it? Every proper technique in this forum seemed to work for me back then. I wondered if there are common factors with people who lucid dream. So maybe to help those people realize the problem we could share how lucid dreaming happened to us.
