Personally, just the look of that web page sent jolts of creepiness energy through me. Not my cup of tea.
Here’s what may be happening in your case: When you read something that suggests, as this seems to, that there’s more to reality than what you casually observe, then it prompts you to pay more attention to your own experience. When you pay more attention, you notice things that you usually overlook, because you’re trying to catch something that you’ve been missing. Life begins to take on a more intense quality. Maybe you could call that “energy”, but it’s just what it feels like to live with attention.
Event if the “dimensions” that this material is talking about are nonsense, it has apparently sparked your curiosity enough to look more closely at your experience, including your dream experience. When you take an active interest in your dreams, you do naturally remember them better and they have a tendency to go lucid. But again, this is just a natural result of bringing attention to the game.
I’m all for living with attention. The best way to get your attention revved up is to live with a curious, questioning spirit. That gets you engaged with the world, intensely interested in it. As skeptical as I am of “New Age” stuff, if it gets your attention cranking, that’s not a bad thing.
