If it is true, and it is, that we all create our own reality then we may think we are in touch with the real world, however we are really only in touch with our own thoughts about the real world. Doesn't that then mean that every experience we think we have experienced, we have really only experienced our own thoughts about that experience.

If how we thought about it at that time has changed. Because now we know more. Does that mean we can allow the feeling to change too. I think we can, once we realise that we are creating the feeling with our thinking . The ego may not like this but we should learn to stop taking the ego too seriously. It is after all how we saw ourselves and our world back then.
