you can make beds now in 0.4.0 update
You dont dream in minecraft you just jump out of bed when you have slept threw night.
yes
You can make a bed or a painting
Minecraft is a free roam game- There are no rules. You don't have to make a bed, they are simply useful to skip the night
No, you need wool.
Make The Girl Sleep in The Bed and Press Shift.
Use the command:/toggledownfallOr just sleep in a bed
Right click where you want to place it, make sure there is enough room for it.
You can use wool for making beds and paintings. I'm not sure about the painting but I know you can make a bed in Minecraft PE
Beds were not introduced into Minecraft until Beta 1.3, so no.
I presume this question was written before the bed update came out, but just incase you didn't know or hadn't updated, beds are now in minecraft that you can go to sleep in at night. Going to sleep in a bed will make that bed your spawn point.
No, but you could make one from your imagination with coloured wool blocks or stone slabs.
