Hey Cardeal,

http://www.dreamviews.com/f79/why-you-fail-wilds-96892/

I read this guide and found it very useful, like you I experienced SP (fairly easy) on my first couple of WILD attempts. However when I didn't experience it for the next couple of days it frustrated the hell out of me, and SP is not a guaranteed LD, which is what you are after in the end. What I noticed was that I was getting too caught up in trying to reach SP, trying to make every muscle relax (as opposed to my body as a whole) not reaching the actual lucid dream.

What changed for me was when I wasn't trying for SP but going to sleep, as is also emphasised in the guide. I had my second WILD yesterday (well, early this morning more like it) and I think I only noticed SP when I was actually in the dream. In the begining the dream was very unstable and I felt a buzzing sensation in my body, which I remembered from SP, and it took a lot of stabilisation techniques. Eventually the SP "feel" disappeared and the dream was more stable.

2 nights ago and in tha last night I woke up in the middle of the night and I was trying to sleep and then SP kicks in! Its very weird and nice the same time! But I dont seem to enter it correctly or entering to a lucid. The best SP of these 2 nights was when I felt that I was laying from my back, but I was laying by side, but it disappeared. Any tips to "catch" it?
The fact that you know how SP feels is superb, that means you have a level of awareness you can use to determine if you have had a false awekening (IE dreaming ^^), but trying to "catch" it should only be a secondary focus I think.

Now bear in mind I am noway of an expert on the matter so you should read the guide, written by an author much MUCH more competent than I. The reason I reply is that your mindset seems very much like the one I had regarding "chasing" SP, which led to me being frustrated, loosing sleep and even my non-lucids were short and blurry. Maybe you can skip this step all together ^^.

Trust in your awareness, you will recognise SP when it comes, after all SP is an indicator that you are on the right track, not the end goal, when I got that in my head and focussed on falling asleep I had my second WILD . Oh and I know the excact feeling regarding SP, it is sort of weird, but nice ^^
