Problem when trying to lucid dream
Hello,
I have been lucid dreaming a couple of times, but they came up randomly so I didn't force them.
When I tried to lucid dream on purpose I had this problem, my heart started to beat really fast as I was trying to get into it.
I was laying on my bed and I was pretty relaxed, and I whispered for myself ''I'm going to lucid dream'' for 1-2 minutes, and then I finally felt I was going into my dream.
The problem was that as I was falling into my dream my heart started to beat faster and faster gradually. This is the first time it happened and it all started with when I tried to lucid dream as I mentioned.
My heart started to beat so fast that I had to breath with my mouth so I cancelled the 'attempt' to lucid dream.
What is the problem?
*Note that it does not occur when I sleep normally, just when I try to induce the dream with the method to repeat the words ''I want to lucid dream''.
Thanks.
Edit: Forgot to mention that I trained myself to remember atleast 1 dream per night, so I should be able to handle the lucid dreaming.
