Imam Suyuti's "sharh-us-sudur" is replete with anecdotes of this nature. It's a must read for every sunni. English translation was posted here.
When sahabah asked about the dead and if they hear, RasulAllah ﷺ affirmed they did but don't reply. Alahazrat says, this means they don't reply in a way that we hear it. Otherwise they DO reply. Sahih hadith prove that they reply. E.g. the hadith about Mus'ab bin Umayr that he will reply to anyone who makes salam till judgement day. Alahazrat says, and us not hearing is also not for everyone. Many pious men have heard the dead. He then presents narrations from sahabah about the martyrs speaking and being heard such as Amir Hamza. رضي الله عنهم
