does dreams come true?

the excitement is gone. the feeling has walked away. what exactly does the dream means? someone tell me please, that it is just a dream and it's not gonna happen in the reality. why am i feeling so scared and no confidence in myself at all? unexpected things come along the way and i thought i could face it bravely. but i never expect that actually, i was too one-sided. no tired to run away anymore. stuck in the middle of nowhere, didn't know what i should do, let to face the world alone. i seriously don't like this lonely feeling.
