2 year old able to recall nightmares

My poor buddy has been having nightmares and he could finally tell me what about last night! During his nap yesterday he sat up, pointed to a spot in his crib and was yelling "no" over and over. After a short time he laid down and fell back asleep. Last night at midnight he woke up screaming. I went in and found him on the opposite side of his crib curled in a ball pointing and screaming at the same spot of his bed. Honestly this freaked me the F out so we went back to my room and I woke my husband up. I took my son back to his room to see if there was actually something in his crib. I put him back in and started touching things and asking if this or that was scaring him. When I touched his pillow he freaked out! I lifted the pillow up and he ran to the other side of his bed scared. Come to find out after some investigation, he thought there was a "bee nest", as he called it, under his pillow!! My poor little man! We talked about it and cuddled for a while and he went back to sleep. Hopefully we have debunked the bee dream!
