I wanted to experiment with the "alarm clock" method.

I set my alarm to 5AM, and had it set to go off every 15 minutes for the next 2 hours.

I placed my cell phone right next to my bed so I wouldn't have to get up. The first time it went off I shut it off immediately and fell asleep almost immediatly after. The second time it went off, I actually felt the onset of SP right before I fell asleep. The third time, I shut it off, and the moment I was back in my sleeping position, I could feel the onset of SP immediatly, and a few seconds later I was in SP with no effort at all almost. I had trouble inducing a lucid, so I just decided to relax (was actually a very quiet SP without vibes and noises), and ended up falling asleep. The fourth time the alarm went off, I felt horrible, like someone had taken a hammer and hit me in the head. So I shut the phone off. Soon as I closed my eyes, the onset of SP started again. This time however there were very powerful vibes, and I felt like I was on a rollercoaster. I tried to visualize a rollercoaster while this was happening but no luck. So I just "roll out" and began my lucid in my room.

The only downside was, when I had to wake up, I felt horrible, like I had gotten no sleep at all that night. The first 5 minutes of getting up was hell, but after that I was fine. It was worth it overall.

I recommend this to people who want to experience what SP is like, because it doesn't require you to attempt to "keep your mind awake while your body falls asleep". Eventually your body falls asleep so quickly you'll still be awake before you realize what hit you. Just don't do if you really need a good night's sleep.
