Alright, what is up with my subconscious?

I have had just like 3 or 4 good lucid experiences about say 5 months ago. I left ldreaming for a while because I wanted to focus on other things, I was tired and [insert more excuses here]. So I just dreamt normally all this time. UNTIL this weekend, which was filled with stress for me. I slept for two hours one afternoon (quite rare for me) and I had a ld, without even trying! Anyways it scared me because I was wo heavy that I woke myself up. And today on the morning, I woke up and fell asleep again to another ld, again without trying. And I got scared again and woke myself up. Now why, all of a sudden am I having ld's without trying and why am I so heavy I can't even move?!

You are getting Sleep Paralysis (being heavy), I don't know much about SP, but look it up.

About having lucid dreams without trying, I guess you are just getting lucky :)
