Hiya Fallout!
I have never tried either Calea or Silene, so I can't comment on them.
If you're interested in pharmaceuticals for promoting lucid dreaming, I can recommend three: Hydergine, nicergoline and tianeptene/Stablon. Hydergine and nicergoline are semi-synthetic ergot alkaloids (as is LSD, I'm sure you know). Tianeptene is a Selective Serotonin Reuptake ENHANCER prescribed for depression and irritable bowel condition (serotonin is also found in the gut and is associated with peristaltic action).
Both Hydergine and nicergoline are prescribed for senile dementia and are said to increase the cerebral blood flow by expanding/relaxing capillaries, as I recall. Both are also touted as nootropics.
After taking Hydergine before retiring, I had one particularly vivid dream in which I received a particular letter in the mail that turned out to be prescient. In the dream I opened the mailbox and saw the return address. That next day, I did the exact same thing in 'real life' and experienced a deja vu sensation. Hence, I have come to suspect that at least some deja vu experiences are the recollection of scenes viewed while dreaming.
That implies that everyone who has ever had a deja vu experience has 'seen into the future'. That they, and probably all of us, have clairvoyant abilities. And, those clairvoyant abilities are not actually dormant, they are functional, they are functioning, we just fail to recognize them.
As to how one can tell the difference between important dream visions and the jumbled psycho-babble that surrounds them, I will give you the secret: they are the important ones.
HAHA yeah yeah. Seriously though, that really is the best answer I can give. For me, at least, there is no blinking neon sign with an arrow pointing to significant dreams. It's something I feel. Something (some part of me, I'd guess) goes up-side my head and says (non-verbally, of course) "Hey shite-for-brains, look at this!"
I am confident that such abilities can be learned and refined. Perhaps the lessons I received in using a crystal ball helped, but that's another story...
Here's something to try next time you experience sleep paralysis: Close your dreaming eyes and will yourself to sit up, then stand up and walk away. A few things could happen. You might wake up. You can't sit up (requires will, not muscles). You'll be sleep-walking (doubtful but possible). You'll be having and out-of-body experience (AKA lucid dream).
In dreams, the mind is king and willpower rules!
Nite-Nite & Pleasant Dreams!
