Hi there my friend,
Congratulations on you 4th Consecutive Lucid Dream :bravo: . There are a lot of possible reasons why you had 4 consecutive LDs in a row. First one is Coincidence. The probability of having 2 lucid dreams in a row is pretty natural. But 4 LDs in a row sounds seemingly hard yet possible. The second possible reason, is you're might be a Natural in LDing. But there's still not enough evidence whether you're a natural or not. Lastly, you're just doing the right procedure in Lucid Dreaming. If you do still have some questions, feel free to reply back. Hope this helps
