So today around 3 PM I decided to take a nap. I put on my headphones and started to listen to some astral projection binaural beats. I layed there for 40 min. So something around the 20 min mark my body felt really tingly and buzzing. At that time I was doing the counting method. The tingling was so intense that I couldn't count and focus anymore. I tried to but it was to intense. I felt my heart beating faster and my breathing got heavier. It kinda felt like a asthma attack or something. Anyways that feeling was going on for about 3 minutes and it faded away. After that my muscles started twitching and I had unconsciously moved my leg, so I opened my eyes and checked the time.

So my question is: was I close to getting into SP/Lucid Dream and how do I stay focused during these tingly feelings ??
