Woah that's interesting, I recently started having more lucid dreams and sometimes wish I didn't because they get so realistic.
The thing is, when I was putting my phone below my pillow because I had alarms for the morning, I wouldn't dream at all. I would just wake up with no dreams.
After that I decided to put my phone somewhere far, I started having those long, lucid realistic dreams. So much that I couldn't handle it and decided to sleep with my phone again... lol
But then I went back to sleeping without my phone in the room, I think I'm getting used to it. Would be nice if I could practice it more, to get even more realistic dreams.
