So there are two things to watch out for is. 1 - Lucid dreaming greats like Sageous recommend that any daytime reminders are truly random (instead of exactly every 60 minutes). You may notice that you are already expecting the alarm, right before it rings, after a while. I am not sure if that is a negative to expect the alarm (it feels similar to when prospective memory kicks in), but again random is recommended. 2 - The RC's may start to feel rote and you may find yourself doing the RC without really considering whether you could be dreaming or without stopping to really look around with a sense of wonder. The random alarm helps to avoid this and changing the tone periodically helps as well.
