Tidal Wave

hey all, first time poster and hopefully first time believer

i dont usually try and dissect my dreams nor have i really read much into my dreams in the past but i did have a really disturbing dream this morning and it has been bothering me ever since and was hoping i could get some help interpreting it.

i was on a journey of some kind but i dont know our destination, i was with my 3 year old son and we were on a boat, some kind of small passenger liner out in the middle of the sea, the water was clear and not too rough. and in the distance( a few kms) all of a sudden i've seen this continuos spurt of water gushing into the air and then it turns towards the boat and goes over the top of us. it was really something not of this world, the cylinder of water is huge its about 20 meters in diameter and the water is quite clean/clear. then i look to where the spurt originates and there coming up on the boat very rapidly is a huge tidal wave that is already breaking. Its pretty much 20 times the size of the boat and i dont feel panicked, i have a surreal feeling as the wave is upon us that we're basically, well um "fucked"! but all the same i feeling rather calm within myself, anyway this is the point i wake up and has disturbed me ever since if there was any meaing. Help!
