OK, so I sleep in a bed with someone and they really don't like it when I set alarms to wake up every few hours to practice my lucid dreaming. Does anyone have any suggestions for a way to get up at specific points but avoid alarm clocks/phones? I was thinking about putting my phone on vibrate and putting it in a pajama pocket but I'm afraid I'd dial someone in my sleep.

Are there, like, vibrating watches or anything of the sort that can be had for cheap?

Suggestions/advice/comments are welcome.
