Hi Elai,
Sounds like a feeling most people would like to be able to induce at will and I understand why you want to get back that "strange feeling".
I believe the feeling came from a trigger in your mind and if so you can definitely get back to that place again. You need to clear your mind in a relaxed state and ask yourself how you achieved that magic feeling and your subconscious mind will reveal the answer.
