Art of waiting moves and positional thinking

Hello lichess community,
this is my first real contribution to the game analysis forum. I want you show you the game that i played today. It was an unrated game against a higher rated opponent, which i luckily won in the end but according to the engine i had a big advantage the entire game.

The first 28 moves I nearly played perfectly playing mostly the engines top 3 choices. My opponent blundered a pawn on move 16 which was a cause of his inaccurate move Qa5 on move 11.

Everything went good until reaching my 29 th move i dont really knew what to do and i played a really bad move which i dont know why i even played it.

My question is:
What is the plan in this position on move 29 , what should i do, what should i aim for? The engine says its +5 , but i evaluated it myself as maximum +2.
The engine is only suggesting waiting moves but i was trying to find active places for my pieces.

Thanks for reading and answering!

@Herzogenrauch I think you, made too many hasty trades ur thoughts on that

@Mahith1708 Yes at the end i made the trades, but my question was what the positional idea would be on move 29.

@Herzogenrauch 29.qd1 and trade the "bad bishop" with bh5

Not sure what you mean by "waiting moves" (the only one who should be playing waiting moves there would be Black).

@Herzogenrauch
See the position first by end of move 28. The position is closed with pawn chain on both sides. So this shows there are already some moves that can be played and few good enough.
Now look, you played Nd5 in order to try to open but that does good for Black instead as after giving up exchange to open position is better Rxd5 exd5 Qxd5. The Queen now steps on the longest diagonal and the light squared bishop can help it along the diagonal and White has no new movements as such.
So how could you open up the position?
~ Qd1 seems sensible in order to support the light squared bishop for the next Bh5 move offering an exchange of pieces.
It forces Black to play a specific move or a better move.
If Black captures then Queen would be on h5 square and since g-file is already opened and controlled by White rook, White has attacking chances.
If Black keeps the bishop as it is then also the White would would be on h5 with attacking chances since dark squared bishop attacks on h6. And if Bd7 you gain attacking chances due to open g-file and the move (Bd7) cuts the connection of Black Queen on the 7th rank so something like Rxg7 becomes playable.
If Bc6, then Bg6+ Kh8 (Kg8 leads to Bxh6 sacrifice then Bxh6 Be8+ discovered check and White can bring Queen along the g-file), White can continue with Qc1/Qd2 to play Bxh6 next since Black king is pushed away from protecting the pawn which can't be prevented and if h5 then Bh6 which is can't be captured since Qxh6+ follows Qh7 Qf6+ Qg7 Qxg7#.
So, it's best for Black to play Qf7 which prevents Bh5 as it could be captured Qxh5 simply.
Now Nd5 works since the Queen is given as task to prevent Bh5 so Black cannot afford rook sacrifice Rxd5. Now Black queen is forced to stay on f7 or play h5 sooner to kick away the bishop and the light squared bishop cannot go to other squares because of immediate Bh5 and since knight has entered Black camp it proves to be dangerous if not handled properly. If Black pawn moves, they would be captured. The Black bishop is kind of trapped since Bxh6 would be threat. Black soon finds itself in zugzwang. If Black plays h5 which it would like in order to mobilise the Queen then Bf3 and any move by Black follows Qc1/Qd2 which leads to Rg6 (with the idea of Bh6 Bxh6 Qxh6#). If Black doesn't play h5, then Qc1/Qd2 directly with the aim mentioned in brackets above.
Also the position of Black is cramped and it finds itself in a spot of bother that it would make it play a bad move of which advantage can be taken.
