prophecy of catestrophe? or healing in dreamstate?

These days i am profoundly tired, but i'm still trying very hard to maintain my connection with The One Energy.
I AM a light worker.

the last 2 nights though i have had very strong dreams of major catastrophe.

let me explain.

1st 'dream'
the waters are rising into the middle of the town where 'we' are ('we' are always a small group of 3 or 4 'people' or just awareness of beings). one of the group feels the need to be carried and is pretending to be unwell and unable to walk. it is night time.
we are now on a flying craft, and as we ,look down we see the worlds atmosphere is all toxic and the air is now very poisonous. the toxicity is coloured as a violet swirling dense gas/fog which also has flickers(like lightning) of gold.
we are preparing to go back down to the surface and we find some gas masks to wear. i am aware that many people are getting very sick and dying from the toxic fumes. and not enough gas masks to go around.
we are now on the surface, the sun is coming through and we are walking on a 'bridge' of concrete and the waters are recedingback. the trees are green and i can see blue skies.
the sick friend is now in the hospital trying to get attention for a condition that he does not have. i am telling him that many people are in a genuinely worse condition than he is.
(actually 'he' is sometimes a 'she' but its always the same person.)

2nd dream
much preparation is being made globally for the coming Tidal Wave that will engulf all things. the date and time of this is all known in advance.
'we' are clutching the stair bannisters waiting for the incoming wave.
i am aware that i am also 'riding the wave' as part of this, i sense freedom and cleansing, great strength, yet subtlety and gentleness.
i have made arrangements to meet with someone after the wave has occurred.
my awareness is back at the stairs, we are moved to the very top of the stairs, which are high above and are no longer in a house.

the Great Wave comes and we are submerged for only the time it takes to hold ones breath and breath out. i have no fear, only great expectation and 'sunshine'

the wave has gone, many have 'gone' with the wave, the remaining people are relieved and also 'see' the sunshine.

as i pass an outdoor swimming baths, an ancient huge tree, has been brought up from the depths of the ocean and deposited there.
a strong swimmer has a line attached to a young child and is swimming fast whilst pulling the child along.
