Movie from when younger? - cant think of the name

[Pelican170]

Hey guys,

This is going to be pretty vague but im trying to remember the name of this movie i used to watch when i was a kid, probably watched it around mid 80's to late 80's (i think). Its about a UFO landing in this town and then weird things start happening, people acting different... The kid and his friend(s) know its the aliens but cant prove it and their parents dont believe them. All else i remember is that they eventually find their way, i think by a tunnel, into the space ship. Thats all the memory i have on this. Any ideas?? sorry for the vagueness of this but it just popped in my head and is driving me nuts. haha
