You can conciously choose to give life purpose yourself, if you choose to use it for something good
Without trying though, I guess people learn, and people hopefully enjoy themselves or try to, but that's just a pattern

I agree with you 100%. Unfortunately despite whai I believe these things come into my mind and won't go away untill I ask others about them. It drives me insane really.

Hmmmm, that's odd, maybe some sort of confirmation thing maybe? - but I guess, if it works, in the end it works!

Either way it gets it out of my head for a while at least.

I used to not be able to cope with the unknown, I literally cannot learn anymore about something unless I understand how it works in the first place - this gave me problems in science, because... why should things be like they are and stay like they are? - I mean it comes down to laws of physics, but the most fundamental laws are just laws, there's no reasoning behind why they should exist, because then they wouldn't be the most fundamental laws; there'd be something even more fundamental than that. To me that looks like things like gravity, electric charge, spin, amd why time should go forward. In the end they just are what they are, we just establish the patterns and use these basic rules to explain more complex things, but they will never tell you why the universe even exists in the first place, or continues to.

It's not really the unknown or unexplainable that bothers me. In fact I'm obsessed with stories of hauntings and such. What really bothers me are the things that go on in my mind, the things I see when I close my eyes and the annoying number of times and ways something inside of me tells me to kill myself (not that I ever will mind you, it just gets very annoying). Those are the things that bother me and more often than not drive me to ask myself questions like this.

In the end the living always have control and choice over what they do, remember that. They can make you think and feel whatever they want, but they cannot control you (or others) or hurt you or overpower your will - if they could, they wouldn't be asking, they'd be siezing control of people's bodies all over the place. They put people under pressure until they surrender, but they do give up too, and you can fight back through your mind, possibly win them over. And not all of them are bad. You have to choose which to listen to, and which to ignore - there's no reason why you have to obey any of them

I know, and the truth is that I feel like I'm in complete control. It's just annoying having to deal with things like that everyday. What is hard to deal with though are some of the things I've seen when I close my eyes.

I don't get it when I close my eyes, but I feel things I think... I think all we can do is withstand, argue back with them if needs be, and sometimes if they make a good point, use it. The malicious ones might be trying to bring us down to their level so they don't feel so inferior.

Being alive allows us easy, direct interaction with the living - which is a unique one-off opportunity. And also having a body makes us subject to physical needs (and therefore pressures in life) which forces us to grow and step outside our comfort zones - as far as I know they don't, and they might be slower to grow as people because with that freedom nothing's forcing them to face up to things or work or anything.
 
It seems harder for living to connect with the dead because of the barrier between us and them, but it does seem possible in a primitive way to a limited extent. I think purpose in any exisence would be dealing with whatever problems we can, I think the living and dead are not too much different. It almost seems silly to seperate them, I guess we won't be forever - but then if we enter their realm we'd have to face everything that's been attacking us - maybe lots of people doing that is what ultimatly will deal with the problems those spirits have. Maybe life with it's limited links to those unhappy realms is a tentative, safer step to doing that.
