this is one of the dreams that i have from time to time and everytime i have this dream it adds on little by little.

the way this dream starts is that im in a sewer like place (but not the sewers) on my back on top of a skateboard kind of item i use this to travel since im scared to walk on the ground. its pretty dark kind of like back before they had lights there are torches on columns every few feet. im moving on my board into a hallway and as i go down this hallway i see a child crying and an old lady in a dirty ripped shawl hunched over saying " here take this fish take this female one i have 2 we have to help each other in these times". i go past them to the end of the hall which isnt far from them, at the end is a spiral staircase, my grandma is on it waiting for me to come back for some reason. i get up from my board but i do not touch the ground at all always on my board. when im finally standing i have a bag with a fish in my hand i walk up the stairways to my grandmas house with all my family there as if it was a holiday, i put the fish on a table and i walk straight.

that is the new ending to this dream.i want to know what this means can anyone help me please.

The imagery in this dream seems like it could be very sexual. I don't usually look at dreams from a Freudian perspective, but in this case the sexual images seem really strong to me.

a dark, sewer-like place (I imagine it's some kind of tunnel)
moving into a hallway
the spiral staircase
fish (you know what is said to smell like fish)
the old lady saying "take the female one"

In addition, the characters in a dream are either very young (a child) or very old (an old woman and your grandma). The young child doesn't have a sexual life yet; the older women have already had long sexual lives (I already have two fish) and are now past menopause (fertility).

Your statement at the end of the post, "I walk straight", also makes me think of sex.

I don't know anything about you, not even your age or your sex, so I can't tell how it all relates to you, but it's what seemed most obvious to me.

Knowing a bit more about you might make it easier to understand why you are frightened in the dream.

that was a very interesting way to see this but im not not a perverted kind of person or anything. i dont know why im so frightened of this dream but for some reason this dream scares me a lot and i wake up in a cold sweat and sometime im not able to fall back asleep for a while. for some reason i remember that old lady in the sewer/tunnel and the fish my in hand vividly and makes me feel uneasy.

Having a dream with sexual symbolism doesn't make you perverted. Sex is a basic drive. It's normal for it to be on your mind sometimes, whether consciously or unconsciously.

Perhaps this dream has something to do with a fear of growing old and dying. There is the old lady, and the fish in your hand is cold (because it's cold-blooded), but when we, warm-blooded humans die we become cold.

Do you notice anything in particular that tends to be happening in your life whenever you have this dream?

nope this dream and another one happens randomly it doesnt matte if im sad or happy it just comes randomly

Since it happens randomly and isn't associated with a particular emotion of your experience, maybe it is your unconscious trying to make you aware of a quality that you possess but that you ignore, or an experience from when you were younger that you've forgotten about.
