Meditation 
On our path we have reached the most peaceful place in the whole forest, slow down and inspire yourself.
Do you get the tranquility of the scene? The surreality indicates the changing consciousness during meditation, it feels like you are tuning a bit more into your higher self, who perceives the environment differently than your superficial self.
Near you, you hear the waterfall. The stream comes out a source and is merging again with the lake. The water evaporates again and feeds the cycle. You realize the true source is the water in which it flows in again.
During your meditation you go from a random thinking individual to a part of an experience, that just is. There will come up thoughts, but you redirect the energy into contemplating about the environment.
The experience is indisputable, when you went deep into a meditative state you'll know.
It is okay to exist, the bird is made by the same energy and from the same source as me - some day we'll merge again.
We might not be separate in reality, but in our perspective we are. We are living the experience and see the beauty of being an individual in a world that we created by ourselves, but don't remember.
Meditation is a change in perspective, an inward change, that is also seen in the outer, because the inner and the outer correlate directly - consciously or subconsciously.

About Meditation
Meditation is one word for a broad experience.
Wikipedia says:
"Meditation refers to any of a family of practices in which the practitioner trains his or her mind or self-induces a mode of consciousness in order to realize some benefit"
I'd just say, that meditation is going deeper into yourself, calming the mind and change your consciousness in one.
There are several practices and very free definitions of what meditation is - so we stick to the things that have an effect on us and are willing to experiment a bit, because it is very individual what feels comfortable and is effective.
Do you have your own technique and don't need a new one? Perfect, do it! - if you feel like posting it here, you're welcome!
And don't raise your expectations too high if you are a beginner.
I wish for you, that you'll get the "different feeling" pretty quick.
The first time I tried to meditate, I got really upset, so even that might happen.
What has Meditation to do with Lucid Dreaming and Astral Projection?
As mentioned before, we need to go deeper in ourselves and make us more "functional". We will have hard times to succeed in any spiritual practice if we can't focus on a subject. Meditation is a tool here. We bring our bodies more in a balance.
A clenched muscle will look bad and need more energy in the same activity as a relaxed muscle does.
Ever tried with a uptight hand writing? Its exhausting, inefficient and tends to mistakes.
Did you realize, that you have a uptight hand when you try to write something quick and are stressed? This is an example for the outer correlating with the inner.
The same goes for the mind - a relaxed mind, is not just more functional, it makes a relaxed body, which is a starting point for exercises regarding Astral Projection, Lucid Dreaming, Chakra work and other things.
You might even consider to meditate before going to sleep, in case you can't get a sleep.
We'll do most of the exercises in the afternoon, so that we can take much of the benefits with us into sleeping time.

What will we use?
I will show you 2 exercises of meditating and 1 example of a small exercise that shows you how variable meditation is.
As said - if you have something with what you are already comfortable, stick to it, we don't need to reinvent the wheel, just to come out with the same.
If you feel like experimenting you might try them out anyway.
Before every meditation, you use the "Breathing for Relaxation" - exercise ( 3.3 ).
It is sort of a meditation, and helps you to go much quicker in your desired state.
