Do you feel particularly more creative at a certain time of day?

I’ve noticed that I tend to be incredibly creative just before I go to sleep and through noticing this I’ve realised that it’s not just creativity…I seem to be more open-minded, positive, open to new ideas, possibilities for the future… I even tend to have ideas of fantastical proportions and think that they are quite reasonable… particularly when compared to how I feel the following morning…which is quite contrastingly negative and closed and I find myself thinking things like…why on earth did I think that would work???

Having said that I have actually had some of my greatest ideas led in bed that have come into fruition..It’s not just in bed either… it seems the evening is generally a good time and the creativity accelerates closer to sleep time :-/

My mentality seems very different at this time of day (and I must stress here that no alcohol or other ‘drug’ is involved! lol) So I wondered whether anyone else experiences this phenomenon and if there is a scientific explanation for it… or any alternative ideas why this would happen
