Last night I was trying the method of staying still for an extended period of time until your mind sends the signal to your body to change positions to see if you are awake. This method worked perfect (I Think). So after 5 minutes of my mind telling my body to move I fell into this really weird state. It felt like my arms were coming out of my body and I was lifting up. I was like sweet balls this is fun! But then after that, my heart rate went up so quickly it kinda scared me and I was like shit, this isn't safe I could have a heart attack. So I ended it and woke up because I pussed out and was scared that my heart was going to explode. Is this normal to feel when entering a lucid dream?
