Yes, it is “possible” but we only see one example of this in Scripture so it is most definitely “the exception to the rule.” In 1 Samuel chapter 28 we see King Saul finding a woman who was a medium (one who claims to communicate with the spirits of the dead) and having found one he asks her to have a séance to bring one up from the dead (verses 7-8). The medium was afraid for it was punishable by death to do so but Saul assured her that “no punishment shall come upon you for this thing” (verses 9-10). The woman then asks who she should bring up and Saul says, “Bring up Samuel for me” (verse 11). We read next in verse 12: “When the woman saw Samuel, she cried out with a loud voice.” Why did she do that? Ah, because she was used to bringing up EVIL SPIRITS (demons) who would impersonate real people. But in this case, she was afraid for she saw “an old man coming up, and he is covered with a mantle” and Saul knew that it was indeed Samuel the prophet (verses 13-14). Samuel then asked Saul, “Why have you disturbed me by bringing me up” and Saul responded by saying, “I am deeply distressed; for the Philistines make war against me, and God has departed from me and does not answer me anymore….therefore I have called you, that you may reveal to me what I should do” (verse 15). Samuel then rebuked Saul with these words: “Why then do you ask me, seeing the LORD has departed from you and has become your enemy” (verse 16). In verses 17-19 Samuel reveals that the Lord would deliver Israel into the hand of the Philistines and that he (Saul) and his sons will die tomorrow. If you read Samuel 31:1-6 you will see the fulfillment of Samuel’s words to Saul.

Again, we will not find another example of God allowing the spirit of a human who had died returning to speak to the living. God had strongly condemned anyone who would try to speak to the dead (see Deuteronomy 18:10-11) and all those who did were either using deceptive tricks or they called up evil spirits (demons) who impersonated the those who had died. There are those today who still pretend to have the power to bring up the dead and they will “reap what they have sown” come judgment day.

In closing, we have an example in Luke chapter 16 of a rich man who died and was in torments and he asked if one could return to earth to speak to his brothers so they wouldn’t end up in this place of torment. In verses 27-28 he asked, “that you send him to my father’s house—for I have five brothers—in order that he may warn them, so that they will not come to this place of torment as well.” What we read next sheds light on your question: “But Abraham said, ‘They have Moses and the Prophets; LET THEM HEAR THEM.’ But he said, ‘No, Father Abraham, but IF SOMEONE GOES TO THEM FROM THE DEAD, THEY WILL REPENT!’ But he said to him, ‘If they do not listen to Moses and the Prophets, they will not be persuaded EVEN IF SOMEONE RISES FROM THE DEAD’” (verses 29-31). We learn here in unmistakable words that God DOES NOT SEND PEOPLE BACK FROM THE DEAD TO SPEAK TO PEOPLE; He speaks to people through the Word of God! God allowing Samuel to return to speak to Saul was the “sole exception to the rule” and in that solitary case it was a solemn message of judgment that struck instant fear into the heart of Saul (see 1 Samuel 28:20). God’s Word now proclaims to all who refuse to believe on the Lord Jesus Christ that they will be condemned to eternal judgment: “He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of only begotten Son of God…He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him” (John 3:18 & 36). Has my reader heard God’s Word, and have you believed on His Son?  (DO)  (712.1)
