It's complex and varies for everyone. The reason why we dislike talking about it, because it might give you false expectations, and those expectations can hinder the process. It can make you miss the forest for the trees.
Truth is, everyone has some level of spirit sense by default. For some people it is slightly active while for others it's dormant. What you need to learn is; how to direct the energies into your spirit senses properly, and how to cultivate the awareness to "notice" it. They call it "6th sense" for a reason. The spirit world doesn't even appear visually at first in most cases. First you merely "feel it". When you can see and hear it then it's usually a result of a "synesthesia" between your senses. Your sixth sense and your mortal senses merge. 
Might talk about this more later, but it is a touchy subject in occult circles which requires a long write up with diagrams and explanations
If you do it wrongly and with false assumptions, you might become delusional or insane. If you do it properly the true nature of reality appears bit by bit.
This is why unlocking it with practice is more beneficial than forcing it open. Because that way you will learn to adjust your senses gradually instead of falling into a downward spiral of paranoia, anxiety and delusion. 
It happens on this board quite regularly and it's quite depressing to watch how the mind of some Anons fall into complete turmoil week by week
Opening the spirit senses is child's play compared to what comes after it. The ability to deal with the other side is what separates the magician from the schizo. 
And currently I am quite reluctant creating more mindless schizos for this board. Once I can see your dedication and your "inner fire" manifest, I might give you a little push, but currently it looks like you just want to leave this world and go to lalaland and never come back. A desire for adventure and wonder is not enough for spirituality. You need dedication and resolve for it. Otherwise you will lose yourself quite fast.

If nothing works for the next 2 weeks then might revisit your case. But seriously, you will need to start somewhere. Learning to walk the path by your own volition is far better than starting out because demons are chasing you around until you take spirituality seriously.
It took a year to stabilize eggAnon. I don't want to restart that cycle again.
