Hi Verre! - congrats on your latest lucid (and wings ) - I had a very similar dream to yours almost exactly 2 months ago when I restarted playing around with the vibe signalling and first began the method described above. I had a dream the vibe had gone off, so I did a reality check - in my case as above - starting the audio on my mp3 player, but the audio came out all garbled so I realised immediately it was a lucid dream (a failed electronic reality check). After awakening for real shortly after I checked (in real life) the timer on the vibe alarm and found it still had 3 minutes to go in its 24min cycle so the initial vibe had occurred only through expectation! As FryingMan said the anticipation factor is very powerful - but I found this only happened the once, when the novelty and 'weirdness' of using the vibe was still high. Its interesting that you've had 2 incorporations of the vibration (one real incorp, one expectation generated) - but neither time did you do a reality check after the vibe went off! you might find it quicker to get lucid from the vibe if you associate the vibe with reality checking - just a thought.

FryingMan - thanks the contribution - the 'partner factor' in lucid dreaming is an under-rated topic I think! Those who are happiest lucid dreaming have the most understanding partners I think This tech has worked well for me and its all done without getting up or disturbing my light sleeping wife - at least so far.....
You were asking about the vibe devices - I think there are more and more of these available. Verres sounds very good and customisable. The invisible clock II is also very flexible and is also very small and light, its about the size of a match box. I found it really easy to sleep with and also, crucially to wear in my sock during the day without any one else knowing it was there. That way I could do daytime practice of doing reality check whenever the vibe went off without any one else knowing as its pretty quiet.

DoubleHelix - wow! - you ordered the invisible clock II - cool! I hope it works well for you! It takes a day or so to get used to programming it - and if you wants any more hints or help I will do as much as I can to help - and now Verre is using her device they'll be another opinion as well. Be good to all be experimenting together! My feeling is - it won't be long before you get a lucid from it - good luck!
