How do I understand the meanings of different mystic experiences during meditation?

Question: While I am meditating, I saw the light is being taken out from my heart. I had similar dreams that, someone is cutting my head and light is being poured out from my head instead of blood. I also dreamed twice that, I am flying up and up through rocks. I have no control over it. In the end there is light all over. First time I dreamt of it. There was someone scary standing with red suit in the light. I felt so scared. I started praying the god then I woke up. Second time I was praying through out the dream. I didn’t see the red suit person, then I woke up. I don’t understand all these meanings. I was hoping may be you could help me sir.
Ps: I don’t meditate regularly. Whenever I feel like it, I do it

Answer: Don’t meditate between eyebrows. Meditate in the heart. It is better to consult some experts in person.
