Ok... im not an oracle, divinator, or anything like this... but i could outline some important things from your dream...

It seems like you have (or had) a perfect life, everything is good, and you is/was a bit bored because of it. ("my dream has a boring feeling")

Then, all girls you loved take you down to the sea. You and they are smiling, and also going deeper and deeper, without realizing it. Until it be too late.

Thats the main things i did see in your dream... i wont put any meaning to it, because i think the meaning is clear enough. Also, i dont want put my own ideas into your mind. So, read whatever you can from what i outlined from your dream...
In my own view, its a dark, somber and foreboding dream... but as im a very dark and even morbid people, maybe my own judgement is being biased by that. So, have your own conclusions...
Anyway, i hope everything go well for you. Good luck! :thumbsup:

EDIT: i just did see your post... when i have a break longer than 2 days, my dreams start to be very bad... many of them are nightmares (what i never have usually)... so, it may be simply lack of weed... the solution? Keep smoking! :jointsmile:
