Hey there!! Welcome to the forum...reminds me of my first post. (verymuch!)

Similar to you I had very vivid dreams as a child and lots of lucids...then my dreams changed and instead of being light and full of wonder, an odd element seemed to creep in...for a while! Fear not!! I too would have those jolts of energy lying in bed. One of the realizations that helped me most was the understanding that (save for a burglar breaking in) everything i experienced at night were merely manifestations of my own self. Every feeling, dream character, sensation....and trust they are all very "real" in terms of experience....eminated from my own being. Being able to hold this thought while in a dream and bathing in the wonder of how that could be possible and yet, be so much more real than I could imagine, yeah....words can't describe!!! My best advice would be remind yourself of this, take a breath, and prepare to enjoy.

With a little effort you will be able to influence your dreams, gain understanding into their nature, and in time achieve hightened levels of awareness and seas of other-worldly experience!!
