Imagination and Hallucination

When I got high with Taylor I tried to lucidly hallucinate (which i guess is just imagination?) I managed to see a toadstool and grass where there was a picnic table and a bunch of woodchips. It was faint, but it was there. Then the spacial perception of the coals on the barbeque were so fucking cool. The cartoon like focus was switching between the right and left, or front and back. Is there really a difference?

This relates to dreams because... I remember talking to Talyor and looking at a red wood fence and loosing focus on the conversation and seeing a car headlights in the fence. I can't remember this ever happening in real life. I'm pretty sure it was a dream. I guess I'll never really know which ones real and which ones not? It made me realize though, that the foundation for a lot of my beliefs, my proof, all happens in dreams. So when you start discussing these things with people, its hard to back yourself up, when they haven't been where I've been. I don't know why I switched to second person there. Thats funny.
