Well.. Look mindscalt , if you meditate while you are tired you will sleep faster but you wint concenerate like while energized , because once you meditate while tired your mind will just want to sleep as its exhausted , so its really harder to meditate while energized but chances are WAY more.

Is it easy to meditate when your tired then when you are fresh during the day?
I notice this because i most of meditation have been during the time I'm tired and easy to lucid dream and remember my dreams, but when i mediate without being so tired it is kinda hard to focus. Do i need to practice meditation during the state when I'm not tired to get used to it?

Hi MindSculpt,
Because you are practicing meditation regularly, you will encounter such things more often now on, So try to use some Astral Projection techniques to increase it even more :)
Reading your experience, If felt that it is a sleep paralysis where you missed your astral projection by going unconscious again :)
Try, Enraged master's new technique once and you will surely get success :)

Also its good to meditate before studying you know , it helps alot! , try it out :)

If you get scared while Astral Projection , Just stay calm & try to manipulate whether its just your imagination or its the real one, If its your imagination then when you stay calm you can't hear those, If its real then just try to avoid or try to acquire some positive energy so that you will get into higher Astral Planes. No demons, no negative things in higher Astral Planes

Not sure where to post this but here goes...

I would like to know some information regarding crystals and gemstones and their metaphysical properties.

Is it more effective to carry around one stone with you all the time or to carry a variety of stones in a sack or something?

How long should you leave them out in the Sun for to charge/energize them?

And if I posted some pictures of the ones I have could you guys identify them for me?

Oh, and what is the most effective way to merge or absorb the energies that they give off?

The most important thing in my opinion is letting go and developing your own experience. I believe meditation can be self-defined. Try not to worry yourself over bothersome thoughts either when meditating, just acknowledge it and continue becoming one with consciousness.
