I don’t know if this is the right board to ask on but if not, a nice mod will move it 
I’ve been reading about HI and HH but just can’t quite comprehend what it is. Can I please get a nice simple yet comprehensive (If that’s not a contradiction) explanation of these concepts and how they can be “exploited”.
Thanks in advance guys!
HH = Hallucinations, like seeing something that isn’t there. Example: You open your eyes, and notice that it’s bright outside, or in the room, which obviously there wasn’t before.
Or you see something that isn’t there, and it can be moving around, and you could be hearing it.
Common belief is that it’s always scary, it is indeed not. It is what you make it, which means if you really expect it so bad to be scary, it will usually get scary, now there are really two kinds of HH’s, I’m really not talking about dreaming state, cause I wouldn’t call that a HH, rather a dream. But HH’s isn’t that common from what I know, if you get them try going more into them. Really what I can understand a HH is, it’s your imagination transferring a thought to reality, like if you where to think really hard about walking out in the nature, and then flip back to ‘looking inside your eyes’, you could sometimes, if in the right state, see the nature, like you would be there.
HI = And image, if you where to do WILD, and after a while just ‘look’ inside your eyes, usually an image will come, I do this all the time, I get the strangest things, but they are made very easy from things you expect to show, if you see something little round, and you think it’s a face, it will usually become a face, and is it a friendly or a bad one? You kinda decide. I used to have these really frightening HI’s before, faces that was sad and scary, smiling like they where about to hurt me. But not anymore 
You can use HI’s to focus on WILD, it keeps me awake, sometimes you can see beautiful things. It’s a little harder to get HH’s, and if you do get them, it would be in a later process. When you get the HH’s try watching them, calm and relaxed. If you get any strong emotions, it will fade away. After a while you can go into the HH’s, but then it wouldn’t really be a HH, rather a dream
How to go into HH’s? Concentration, i usually get lost after my first HH have faded.
To be a bit more spicific then ulv,
HH is Hypnagogic Hallucinations.
Hypnagogic means it is happening when you are going to sleep. You are in the transition stage between awake and sleep when the Hallucinations happen.
Hallucinations can also be sound, feelings and taste. Taste doesn’t happen very offten, but sounds and feelings do. The feeling of falling, or floating are very common. Hearing voices or loud sounds is also vary common.
HI is Hypnagogic Imagery, i.e. visual hallucinations when you are in the transition stage to sleep.
For most people HH is not a big problem because by the time it starts, they are already half asleep, and don’t pay much attention to it, or don’t even notice it. Sometimes they wake up because they thought that they were falling, or heard someone talking.
It is a topic for LD’s that try WILD, because in WILD, you try to keep your mind awake while your body goes to sleep. That means that youj may, for the first time in you life, be aware of the HH. It can be scary if you don’t know what is happening, but if you know, then you may need to work at remaining calm because you know that you are getting close to falling asleep, and maybe close to an LD. 
Hope that helps.

Thanks guys, both of you. One last question I will ask though, are HI/HH only possible or only an issue through WILD? How common is it to see this Hypnagogic Imagery while going to sleep? I often imagine situations in my head and think to myself “where did that come from”, but is this the same as HI? Sorry if I’m making little sense here, it’s late and I’m tired, but also pretty curious.
HH and HI can happen every time you go to sleep. It is as I said, most people don’t notice it because they are too far gone by the time it happens.
If you are close to sleep, and you see images, or even complex patterns, then it is probably HI. If it is something that you are activly imagening, then it is probably not HI. The problem is that the line between the two can be very thin. If you take a look at the VILD tech. you might be able to uderstand it a bit better, or maybe not. It is not real easy to understand.

Haha, got that right. I’m beginning to understand though, thanks.
