About OBEs

I know these questions have probably been asked so many times. Sorry about that. I'm getting curious about OBEs.

What are the stages/signs when having an OBE?

How would you know if you had one?

I keep hearing people talking about planes? How many planes are there?

Is it possible that some false awakenings are OBEs? Ex] Wake up in bed, walk around, realize your dreaming through RC, but everything looks just like how your house looks like?

What would your vision be like? Is it normal, or different?

What are your experiences like?

Are OBEs safe or dangerous?

What was your first OBE like? How long did it last? Is it ok to be long distance exploring, or would that cause problems?

Questions About Guardians

I just have to ask this. It's been running on in my mind. Every time I have been scared, something would happen. Or, when I'm trying to find something, I'll hear a ringing sound, and turn around, and there's the item that I was looking for. Is it possible that my guardian was doing that? When I get scared, I sometimes think of my guardian and God, and ask them to protect me. When it happens, I feel huge amounts of energy, and I feel safe. I know that sounds crazy, and silly, and >.< ugh, I don't know why I'm even mentioning this. I told myself I wouldn't ask about these things. Anyway, Is it possible that my guardian was really there during all those times? I also get extremely lucky. No one knows why. Could that also be a reason? Or are all of these just coincidences? Also, when I go to bed, I will hear that sound when I'm going through SP, or a buzzing sound. Its a weird sound, it is kind of like a ringing/buzzing sound.

I know this is silly, but there have been times where my legs would randomly vibrate. Other times, I can't feel my own body at all. I never twitch, but when I'm in SP, my leg, or arm or something will randomly twitch. Other times, my leg would feel like its popping up at random, or arms. I had a time where my whole body would vibrate.
