Hey there. I just, 15 mins ago, decided to try to WILD. I was listening to music (I thought, it wouldnt only help me stay awake, I could also take it as a time reference, 2 songs -> 7 mins and bit more, thats what it takes in average to fall asleep).
Its me third attempt, none of my past attempts were succesfull. But this time, I started feeling different when I reached the third song. I kind of started feeling a bit colder, and a weird feeling I probably couldn't explain; point is, I noticed tgerr was something different. I was cool with it, until I started to feel like I was spinning, all this with my eyes closed. This kind of excited me at first, but then I felt like I started spinning faster, and faster. It ended being scary, but I was still willing to keep on going, until the spinning was insane and it started randomly changing direction violently. I felt like what you fastly move your head from right to left while headbanging. I freaked out, and opened my eyes. I am still shaking a bit, and I'm bit scared.
What went wrong? Is it normal, or common? Can I avoid feeling like I spin?

Thanks so much.
