^ Sis, the above hadith are about dreams experienced during sleep.
If we do daydream about nice things, we should dream about seeing Allah swt in the here-after.. What more could inspire us to better ourselves? But as human-nature goes, when we do dream of nice things in the dunya we should ask ourselves if we are worthy of them in the eyes of Allah swt. Are we striving hard enough to please the Bestower of Blessings? It's no good hoping for anything good if we don't do good.

Allah subhana wa ta'ala says:
"Is there any Reward for Good - other than Good?" (Quran: 55:60)
~~~~~~~~~~~~~~~~
And due to Allah ta'ala being the All-Knowing, we may not receive something that
we think is good for us. So whether our dreams come true or not, we should accept it as Allah's will and say 'alhumdulillah Rabbil alaamiin' in all circumstances. That way Allah will be pleased with us for being patience and praising Him in all times as Allah subhana wa ta'ala Himself says in the Qur'an:
"Allah loves those who are patient" (3: 146)
“Only those who are patient shall receive their rewards in full, without reckoning” (azZumar:10).

Umm Salamah (rA) said: I heard the Messenger of Allah (s) say: “There is no Muslim who is stricken with a calamity and says what Allah has enjoined – ‘Verily to Allah we belong and unto Him is our return. O Allah, reward me for my affliction and compensate me with something better’ – but Allah will compensate him with something better” (Muslim).

Suhayb (rA) said: The Messenger of Allah (s) said: “How wonderful is the affair of the believer, for his affairs are all good, and this applies to no one but the believer. If something good happens to him, he is thankful for it and that is good for him. If something bad happens to him, he bears it with patience and that is good for him” (Muslim).

Narrated Anas bin Malik: The Prophet (s) passed by a woman who was weeping beside a grave. He told her to fear Allah and be patient. She said to him, “Go away, for you have not been afflicted with a calamity like mine.” And she did not recognize him. Then she was informed that he was the Prophet. So she went to the house of the Prophet and there she did not find any guard. Then she said to him, “I did not recognize you.” He said, "Verily, the patience is at the first stroke of a calamity” (Bukhari)
