Welcome to the forum! This place is all about dreams. Mostly lucid, but in the subforum Dream interpretation in forum General lucid dreaming, you can ask for some insights about the meaning of your dream.

OK, so when you wake up but can't move - that's most likely sleep paralysis. It happens, when your mind wakes up before your body does and you are not released from SP yet, as you normally would. Try to relax, change your breathing and wiggle your toes and fingers. That should help. Or just go back to sleep. You can read about SP in Dv Wiki and in tons of threads.

Dreams usually reflect our everyday lives, thoughts and worries. When we see our departed loved ones, it could be because we think of them, or they are really visiting. (Forum about topics like this is Beyond dreaming). But the best person to interpret the meaning is the dreamer himself, since the symbols in dreams may have different meaning for different people.

If you interested in lucid dreaming (dream, when you realize you are dreaming and often can take control of your dream), please check out the DV Wiki for induction techniques, like DILD and WILD. Good luck and Happy dreams
