It won;t end up with lucid dreaming or anything like that right?Because I don't want to get involve in things that may seem a bit confusing......(I am referring to meditate to sleep not dream yoga).. .
From what I've learned if one is really meditating before sleep, it will naturally lead to the state of Dream Yoga. Also, the experience of authentic "Lucid Dreaming" or Dream Yoga is said to be calm and blissful, accompanied with an increase in clarity; and clarity is we could say the opposite of confusion. So I wouldn't worry, the main point is to relax.
It does not involve anyone else,just worried about any potential karmic consequences...
If you've not yet received any Empowerment or Transmissions, there are purification practices that anyone can do related Sutrayana Mahayana.
