yes it is, don't worry about
It won't do you any harm - but you should really talk to someone and work out why you cry yourself to sleep. It's not 'normal' behaviour - and there must be a reason for it.
No
yes
If you are not a normal person it is impossible to be yourself in a normal way.
Try to imagine that tomorrow is a normal day, think about what you'd do on that normal day. When you do finally wake in the morning you'll find yourself believing that it's not christmas.
If you are having trouble sleeping at night you can get yourself to sleep by drinking warm milk or chamomile tea
because victim might die. why you want victim to die in snake bite?
yes
No because it could bite you in your sleep!
First you have to find one, then you can cut yourself in its presence then its hunting instincts will take over and it will bite you. Or you can simply say "Bite Me", and I am sure that it will pleasurably bite you.
It's practically normal to think of anything when you sleep in the bed at night
