Hi,
I've been using an alarm app for android named "alarm droid" every Fri-Sun to practice lucid dreaming. Most of the time only once per week I awaken. I usually set the alarm 4 to 5 hours after I go to sleep.

Can anyone tell me if I'm better of setting it to three to four hours after I go to sleep?

Also tonight I'm going to try to put my phone under my pillow on 100% volume to see if it'll awaken me during the night.

Also I'm setting it every half an hour to wake me up.

Thanks.
