I got a dream where i saw some like around 2 to 3 penguins playing near the shore of the sea,where waves are coming mildly.What does penguins in dreams mean?

Hmm penguins...  It depends a lot on the rest of the dream.  I would be looking at them as birds that swim, which would indicate you like flying in emotion (or the unconscious) somehow.  Specifically how that could fit I am not sure.

They are also a 'tight knit family' huddling together for warmth.  So it could indicate tight family as well as loyalty in relationships, I believe that penguins mate with one partner for life.

They also can be seen as playful, and that is what they are doing in this dream.  Could be indicating a positive playful relationship within a tight family circle.

Thank you Rook.Good,it is positive one!
