weird dream, please help me interpret

[dreamconfused]

last night, i dreamt that i was on an old and unused bridge, hand in hand with my son who was very happy. the bridge was on top of an old river with crocodiles around it, so i thought crossing the bridge would be best for me and my son. when we were almost at the end, i saw two huge crocodiles which were sort of mutated and big, and i felt that they detected us, so we ran for it. my son and i hid in a little corner on the right side of the bridge that has a red gate, and felt safe. after that i felt people coming to save us, and i saw that we were actually crossing the river, and i even stepped on the head of one of the crocodiles to cross it. then the scene changed and i saw myself with my fiance, we were going to ride an suv-type vehicle. but since the only one seat is free in the middle row and one in the back, he sat in the middle row beside a young woman, and i , in the back, in front of a smiling grandmother.scene changed and i saw myself steps from my house, saw my family there. then i saw my fiance again , sleeping on the ground, with a hole under his head. i placed about 3 pillows underneath his head, and saw the vehicle coming back and in the dream i was thinking if i should join them in the vehicle or stay home, since i felt a little tired and didn't feel too good.
please help me interpret this.thanks!

Hi,
A bridge means someone who is useful for everybody.Crossing a bridge means achieving a wish.

Crocodiles are a few criminal people, they insult or chase a gate means a big man you will refuge.

Good luck.
