I have some healing crystals that also need cleansing What can I do that‘s easy to do for a beginner? Even plants die in my room
Throw those crystals out before you get into this nonsense any deeper. Otherwise, you'll end up talking to yourself while normal people stare at you, trying to politely steer the conversation away. I've seen it happen. The teachings of the New Age are about inducing and encouraging states of hallucination. Stop levitating and come back to Earth while there's still time.
Clean your room, open and window and think happy thoughts.
There is no negative energy. At least not the kind you are talking about. No such thing as healing crystals. Water your plants. Consult an expert in house plants before assuming some mystic force is killing them.
