Dreams scare me. Good and bad.

Sometimes they seem so real. Within the past 2 weeks, I have had 4 dreams where I have woken up in a complete state of disorientation. Mainly because each dream has involved someone I havent seen in recent months.

I wake up a bit freaked out. I wonder why they are in my head. Is it a sign? Will I see them soon? Should I call them?

Its the whole reality of the dream. I know they are real people who exist. I am myself in my own dream, with my feelings and thoughts. Then when I wake up, everything is gone. My feelings, the people, and the moment.
