I agree with your observation about the market. There can be a small correction before the halving which can take us to the 25k level again. This correction won't be significant so selling at this level and buying back when there is a dip won't make much difference. However there isn't any guarantee that there will be a dip before halving. If our prediction proves invalid we will miss the chance to buy at this level either.
I would rather not sell at this level than later not have the opportunity to buy back at the declining level you are referring to. So I would prefer to continue holding rather than selling now and will also try to buy when there is a price drop as you say, although not with much force. But buying when the price decline has occurred is still a pretty good option for everyone so there's no harm in taking advantage of it, just because the guarantee of a decline is still uncertain. I will continue to keep the Bitcoin that I bought previously.
You can plan for your own way of executing the situation. What i think is that there won't be any significant drop and even if there will any it won't last for long. The market will recover quickly and price will back to its normal position again. The best we can do is accumulate more if price made a correction because this dip can be the last significant dip we are going to see.
