You don't have to get info just through visuals, and all that.
Sometimes some hear things, or just get feelings, or a knowingness about certain things.
Sometimes its a mix of a few, or all of the above.
But the more you practice visualization, the easier it becomes and the more it seems real to you...
You literally are exercising your psychic Pineal gland when you "imagine" and visualize, and its like a muscle....
In most people, the Pineal is rather atrophied from non use, but some people because of the amount of certain things they do, like meditation, visualization, or deep theoretical thought (like a theoretical physicist or mathemitician) they strengthen this particular gland and its secretions.
There are artificial ways to open this center up, but these can cause a lot of harm, because they force it too much.... Its like giving a weak and atrophied heart a shot of adrenalin without a good reason.
LSD, and other drugs like that will open it up, but are very dangerous so i don't recommend them.
Some have even resorted to drilling holes through the forehead which is called a trepidation, but yeah, don't recommend that one

There is a certain food which seems to stimulate this gland, and i've yet to really deeply experiment with it even though my guidance keeps giving me dream messages about it.
Its called "mummy food" and is just a mix of chopped dried figs, chopped dried dates, with a little (very little) cornmeal, millet, or what not, cooked in water for about 15 minutes on medium heat, then add a little almond, soy, goat milk, or watered down yogurt (i don't ever recommend cow milk because it is very hard to digest because of the Casein proteins and lactose suger).
Tastes good to me, takes a little time to prepare, which is why i haven't been consistent with it. But the times where i ate it for a few days, i had crazy dream activity, which is an indication of an increase of activity of the Pineal gland.
