I remember I had a OBE once, the most successful one I've ever had. I saw a person who said a lot of metaphysical stuff and also ''
oh and we have extended your life with xxx light years and -- more metaphysical stuff which was too difficult to understand --
hm.. you have no idea what I am talking about isn't it.. She was right.

After that she told me ''Go to England!'' back then I've answered her I'm not interested in England but wanted to visit Ireland sometime. However, some years later my friends invite me to travel with them to England... and I did. No Ireland so far.

What I try to say is, I don't believe in aliens at all. But sometimes I have this weird experiences where life forms appear, or they talk about extending our lives or about the future... even if I don't believe in those theories, they appear anyways.
What I have learned about my OBE's and LD's are the following differences:
- LD's in different states of lucidity
- OBE's are always highest lucidity like I am totally awake and can remember everything of my real life
- A LD can happen anywhere and no sensations are needed. When the dream stops, I can feel/see it 'go away'.
- An OBE -always- starts in the room where I sleep and everything looks very realistic, maybe some objects are moved - however: it's still my room. When the OBE stops, it's possible to feel a shock, but that is not necessary.
- In LD's I have the power to change anything.
- In a OBE I can't change anything. Everything is just the way it is. I can maybe fly, but I can't turn a DC into a hotdog.
Also, some believe OBE's are real, others believe it's just something from the mind.
At first I thought that I had died
I had something like this too, a couple of months ago. A friend, who knows a lot about brain states, told me I had a delta experience. It's like the black void, where every sensation/sense/feeling/thoughts no longer exist. If you go just a little deeper, the black void will turn into a white tunnel. And tadaaa, you have a near death experience.

At least, that's the theory. I don't feel like trying it out yet

But that's also what people with a heart attack can experience, everything shuts down - your brainwaves go very deep and you experience something like that. Scientist have found a way to fake this experience, that's a fact - but so far nobody knows if the spontaneous experiences are real. Well ok, they -are- real but what they mean is like if the experience is real as in a real other dimension/level/world.
This has been discussed on a Dutch forum before and there is always a group who believes there are more dimensions/worlds out there and others who don't believe it. The funny thing is, all the people who had these experiences before believe it's very real (also because of some realistic facts, like you heard the phone call) are in the group of believers and people who never had the experience are in the group of non-believers.

And also people who are afraid of the unknown and hope to find some logical explanation are in the group of non-believers.
That's what I saw at a Dutch forum of course, not sure if it's the same over here... but actually it doesn't really matter.
What do you think Bluebird?
