When I read some articles on WILD, it turned out that I've been practicing it for some time, not knowing it's called WILD and used to enter lucid dreams (I just enjoyed the strange feelings). There are some strange experiences, however, and I hope someone explains me what they are and whether they are normal...
1. Usually I aborted the process after a stage where my heart started beating rapidly, driving blood to the head and making it feel like someone was pressing my eyelids. Nevertheless, the feeling was generally pleasant, and I even held my breath to stop it from fading away.
2. Although I relax in the beginning, I find my muscles spontaneously contracting during the later stages, so I have to pay attention and relax them (or just don't pay attention, but then my limbs start shaking after a while).
3. I don't feel paralyzed. It feels like something flows through my body and "electrifies" it (and it happens several times, each time with a different feeling), but I still can move (although if I do, I lose concentration).
4. Even when I felt my eyes going backwards and forwards ("drawing" something in the blackness before them), when finally visions started to appear (although very unstable and rapidly changing) and I even heard a corresponding sound (the sound of a spoon hitting a cup in my left ear, corresponding to what was seen in the left, although it quickly faded away) and I underwent one more "electrification", suddenly I felt a cramping pain in my right leg, so intense that I had to give up. What went wrong?
