Alicornutopia

You have to touch it. Seeing it is just the usual way to successfully do that. Shines can only be made of visible spectrum light even if you are turned into a vampire or something.

Visible as defined by human eyes, or by the transmission window of Earth's atmosphere, or something else? If the first, I'd expect some plants to be unhappy under shine-light, which will be sort of UV-deficient.

As defined by why are you asking me I am not a physics. Some plants may have been thus unhappy, although the fact that the Trees don't sunburn people suggests that the sort of plants they'd have brought to grow would cope with lack of UV.

My impression is that the Trees don't sunburn people due to magic bullshit. They apparently produce ultraviolet light (it's visible at Mingling apparently?).

I’m pretty sure plants don’t really need UV even if they are happier with it.

Also, a better method of conveying information to one’s reincarnation: discuss it out loud at least once per day, preferably twice. Within a week of getting full-time memory dreams, your future self will have the full content of the conversation. Maybe three weeks because they don’t start this process on their first or second life, but the one week estimate does include not mentioning it during childhood and perhaps sleeping less than a third of the time.

Most of that can be accomplished by making sure to discuss last night’s dreams every single morning, and why dreams are relevant. This conversation might need to take place after tea in order for the Dan to form memories of it.

That sounds...kind of like an incredibly huge time sink-to-benefit ratio

That's why I mentioned that most of it could be handled in a discussion that should often be interesting anyway. It does not matter how long or short the conversation is; you spend half as much time asleep as awake so if you have the conversation twice a day you dream it once per night on average; I said once a week instead because of all the days you don’t do this.

Besides, it took years after Sylvi and Avedan started dreaming that they found the cache; I expect that the dream conversation is more worthwhile on average than most pre-cache activities and takes less than one year over the course of a lifetime. If that calculation is off and the dream conversation is bit worth it, keep in mind that it also does not need to be out loud or long. Simply thinking “If this is a strange dream, then you are a reincarnated version of me; come to Lapis, [address], at your earliest convenience” while brushing your teeth should be enough.

One actually gets 5-6 hours worth of dreams a night, not a solid 8.

And apparently the ramp up to 100% past life dreams is a lot slower than I thought, based on what Incandescence!Kib tells Aydanci; my plan might not actually speed things up very much but would probably still help some.

Wait, can shines and shades recognize reincarnations like golems and pets can?

Do the things that recognize reincarnations also recognize alts?
